Although most health complications relating to blood pressure often focus on high blood pressure (hypertension), low blood pressure (hypotension) is a significant issue that deserves attention. Low blood pressure is below 90/60 mmHg (systolic and diastolic). Hypotension can cause shock, a health condition characterized by confusion, weak pulse, and changes in skin coloration. Besides, some people may experience lightheadedness, fatigue, fainting, and difficulty concentrating. Low blood pressure is a serious medical issue requiring adequate attention.

Medical conditions, medications, and age are the primary causes of low blood pressure. Pregnancy, blood loss, heart problems, dehydration, lack of vitamin B-12 in diet, and severe infections are some medical conditions leading to hypotension (Cautela et al., 2020). Besides, Cautela et al. (2020) adds that medications, such as diuretics, beta-blockers, antidepressants, and drugs treating Parkinson’s disease and erectile dysfunction can cause low blood pressure. Lastly, people older than 65 risks developing hypotension. The rationale for age as a risk factor is that elderly individuals are more likely to develop Parkinson’s disease and heart conditions that lower blood pressure. Health problems, medications, and age are the leading causes of low blood pressure.

People suffering from low blood pressure can improve their condition by drinking more water, using more salt, and taking hypotension medications. Increased water intake improves blood volume and prevents dehydration, resulting in increased blood pressure. In addition, taking more salt can help treat hypotension. However, individuals should first consult their healthcare provider to avoid heart complications. Lastly, medications like fludrocortisone boost blood volume, resulting in increased pressure. A person with low blood pressure can improve their health by drinking more water, using more salt, and taking hypotension medications.

Low blood pressure is a serious health issue because it results in shock, fatigue, and lightheadedness. Medical conditions, medications, and age are the leading causes of hypotension. Nevertheless, one may remedy this condition by drinking more water, using more salt, and taking hypotension medications. Low blood pressure requires serious attention, just like high blood pressure.

Regarding losing weight, nutritionists and physical therapists usually recommend sustained periods of healthy eating and exercising. Notably, such activities require patience, discipline, and hard work. However, many people are unwilling to stay committed to the course. Instead, some individuals purchase unauthorized and unapproved slimming pills online, swayed by the “miracle” of quick weight loss. Nevertheless, these diet pills are unsafe and contain dangerous components. Although diet pills are unsafe, the desperation to lose weight makes people become reckless and risk their lives by taking the medications.

Diet pills cause more harm than good. Many weight loss pills have contaminated ingredients, are dangerous, and result in health complications. For example, in recent years, investigations into many weight loss products sold in the United States have found that they contain antidepressants, seizure medications, and laxatives. In addition, some slimming pills contain sibutramine, a stimulant that equally acts as an appetite suppressant. Dedov et al. (2018) reveal that sibutramine affected people’s blood pressure and did not help individuals to lose weight. In addition, fluoxetine is a prescription antidepressant; however, it is a key component in some slimming pills. Overall, the medications are dangerous and rarely work.

Although some people may still use diet pills regardless of their risks, the safest methods for losing weight include eating healthily and exercising. Consuming a high-fiber diet, eating fruits and vegetables, drinking plenty of water, avoiding unhealthy foods, and reducing alcohol intake can help one reduce weight (Miketinas et al., 2019). In addition, being active and exercising enables one to burn many calories, thereby reducing weight. Generally, eating healthily and exercising allow one to lose weight safely.

In summary, diet pills have become popular since they promise miraculous weight loss; however, they are unsafe. Most slimming pills are not approved by the FDA and contain dangerous ingredients. The only safe strategies for losing weight include healthy eating and exercising. People must not look for the easy way to lose weight but should put in the hard work and discipline.

What Causes Hiccups and What’s the Cure to Stop Them?

By Terrie Johnson| Intern and UAB Community Health and Human Services Student

Medically, hiccups are synchronous diaphragmatic flutters or involuntary contractions of the diaphragm and the larynx. After each diaphragmatic contraction, the voice box simultaneously closes, resulting in a “hic” sound (Eroglu, 2018). Hiccups challenge eating or drinking, which may lead to energy loss and dehydration. Although many adults recover from hiccups within minutes, this medical problem can become serious in infants, especially if it lasts more than 2 hours. Overall, hiccups occur when the diaphragm involuntarily contracts.

Adults’ primary causes of hiccups include dietary complications, medications, and some medical conditions. Consuming spicy meals may irritate the phrenic nerve while overeating and could result in stomach distension (Eroglu, 2018). Besides, drinking carbonated drinks and alcohol could cause gas in the stomach, which creates pressure on the diaphragm. In addition, medications such as opiates and medical conditions, including gastro-esophageal reflux disease (GERD), pneumonia, and pleurisy of the diaphragm, may cause hiccups. Lastly, in infants, changes in stomach temperature, swallowing too quickly, overfeeding, GERD, or asynchronous breathing and swallowing may cause hiccups. Overall, hiccups result from dietary complications, medical conditions, medications, and feeding problems.

In most instances, hiccups disappear after some minutes; however, if they persist, a person may adopt some strategies to mitigate the problem. Those strategies include sipping cold water slowly, placing gentle pressure on the diaphragm, biting a slice of lemon, gently pulling on the tongue, sitting down and hugging knees, and swallowing granulated sugar, among other strategies. Although there is no research backing the effectiveness of these approaches, different human generations have passed these tips on to the next, implying they help eliminate hiccups. Normally hiccups go away after a few hours; nevertheless, one can adopt the above strategies to end an episode of hiccups that lasts longer.

In summary, almost everyone experiences hiccups, which is an involuntary diaphragm contraction. The condition sometimes makes it challenging to eat or drink food. The primary causes of hiccups include dietary complications, medications, and some medical conditions. Feeding problems are the primary source of hiccups in infants. Nevertheless, one may get rid of a persistent hiccup by sipping cold water slowly, biting on a piece of lemon, and pulling the tongue, among other approaches. When you experience hiccups, what strategies do you use to end them?

What are Skin Tags?

By Terrie Johnson| Intern and UAB Community Health and Human Services Student

Skin tags are non-cancerous growths that appear like clusters on the skin. Most adults, especially older ones, develop them as they age. The tags are harmless, painless, and do not result in medical complications. Nevertheless, they are unsightly, especially in visible areas like the face and neck. Consequently, an individual may become self-conscious. Although skin tags are harmless, they may affect someone’s self-esteem.

Although skin tags are often small, usually between 1-5 mm, they can become larger (figure 1). They appear as parts of the skin tissue extending outwards, held by a thin stalk (Tripathy et al., 2019). They occur when the extra cells on the top layer of the skin are released. Subsequently, the additional cells in skin folds form harmless growths as the skin rubs against itself. In most cases, skin tags grow in the armpits, eyelids, genitals, neck, and beneath the breasts. In general, skin tags are non-harmful growths that form on the skin due to the production of extra cells.

 An individual should contact a dermatologist for removal procedures. The skin specialist may typically remove the skin tags by freezing them with liquid nitrogen, cutting them off using sharp instruments like a scalpel, and cauterization (Syed et al., 2021). Ideally, a person may try to remove the tags at home; however, dermatologist caution against this idea because one may bleed excessively or become infected. Thus, the recommended skin tag removal procedures include freezing, cutting, and heating them.

In summary, skin tags are common in aging adults. The growths are harmless, but unsightly when they occur in visible body parts like the face and neck. They result from excess cells released by the body. The primary strategies for removing skin tags include freezing, burning, and cutting them. One should not attempt to remove them at home due to the risks of bleeding and infection.

Preeclampsia Prevention in African American Women

Ashley Peoples | UAB School of Education Community Health & Human Services Intern

Preeclampsia is a condition where the blood pressure of a pregnant women increases beyond the normal range. So, how do African American women prevent preeclampsia? The first step to preventing preeclampsia is education.

Maintaining blood pressure is one of the keys to preventing preeclampsia and is something African American should be aware of. The article “Preeclampsia” states women who have a top blood pressure that is 140 or greater and bottom blood pressure of 90 and greater are at higher risk (Karrar & Hong, 2023). The CDC suggests women buy a at home blood pressure machine, and keep it monitored.

Karrar and Hong states “Like hypertensive disorders, the incidence of preeclampsia is correlated to ethnicity and race, most prevalent among African American”. Exercise is another preventive method for preeclampsia. Exercise can improve blood pressure and help keep it maintained. The BMC Public Health states “After a 12-week exercise intervention among healthy and nonactive pregnant women, the changes in resting blood pressure between intervention and baseline were assessed, and the researchers found that regular, long-term physical exercise significantly reduced resting systolic blood pressure” (Zhu et al., 2022).

I encourage all African American women to who are pregnant (or planning to get pregnant) to educate themselves on preeclampsia. I hope that this blog can help many African American women avoid the risks that come with preeclampsia. When we educate ourselves, we make a difference in our own health.

An infrared sauna uses steam or heat to create an environment that will increase your core body temperature. While using an infrared sauna, you’ll sweat, and your heart rate will increase to pump more blood to your skin, which is your body’s way of cooling you down. An infrared sauna mimics the effects of physical activity and provides similar health benefits as exercise (“Health benefits of infrared saunas,” 2021).

It has been shown in studies that infrared saunas can help boost heart health and decrease blood pressure. Researchers compared the physical response of a sauna session to a moderate-paced walk. An infrared sauna can speed up muscle recovery following exercising for improved blood circulation. Infrared saunas can also be used for meditation and help decrease stress, anxiety, and depression. Better sleep has also been linked to sauna use. There is evidence that using an infrared sauna regularly can help avoid the common cold and reduce oxidative stress related to cardiovascular disease, degenerative diseases, and cancer (“Why infrared saunas are ‘Cooler’ than traditional saunas,” 2022).

Healthline (Lindberg, n.d.) has provided some tips on how to use an infrared sauna:

  • Make sure you are hydrated before going into the sauna. You can bring water into the sauna with you.
  • If it is your first time using the infrared sauna, you want to start at 100 degrees Fahrenheit for a few sessions and increase the temperature each session until you reach 150 degrees Fahrenheit.
  • For the first session, start with 10 to 15 minutes. Afterward, you can add time to each session until you reach the recommended time of 20 to 30 minutes.
  • You can dress in whatever you decide. Some people prefer to go naked, and some wear bathing suits.
  • After your session, it is recommended that you take your time and let your body cool down. After your body cools down, feel free to take a shower.
  • It is recommended to use the sauna three to four days per week.
  • Avoid using the sauna if you’ve been drinking alcohol
  • If you feel lightheaded when you stand up while getting out, make sure you get up slowly and sit down once you get out. Make sure to drink your water.

My husband purchased a portable infrared sauna from Amazon to be used in our home. After using the sauna, I feel relaxed, and I feel that it has helped with my weight loss journey. In addition, my husband feels the infrared sauna has helped improve his knee pain due to blood circulation from using the sauna. Everyone may experience different effects from using an infrared sauna. However, it has known health benefits, so it won’t hurt to try it. It can be purchased online, and it can be found in some fitness spas. Have you experienced using an infrared sauna?

Obesity, Overweight, and Simply Walking

By Jessica Feagin, Intern and UAB Community Health and Human Services Student

People who are overweight or obese, compared to those with healthy weight, are at increased risk for many severe diseases and health conditions. These include high blood pressure, high cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, sleep apnea, breathing problems, low quality of life, body pain, and mental illness. Overweight is defined as a body mass index of twenty-five or higher. Obesity is defined as a BMI of 30 or higher. According to the CDC, all states and territories have more than 20% of adults with obesity. The South (36.3%) had the highest prevalence of obesity (“CDC Overweight & Obesity,” 2022).

Physical activity like walking is essential for weight control because it helps burn calories. Adding 30 minutes of brisk walking to your daily routine could burn about 150 more calories a day. Of course, the more you walk and the quicker your pace, the more calories you burn. Combining physical activity and cutting calories seems to help with weight loss more than exercise alone (“Walking: Is it enough for weight loss?” 2022).

Besides weight control, regular brisk walking manages and prevents many conditions, such as heart disease, stroke, high blood pressure, diabetes, and cancer. It also strengthens your muscles/bones, increase energy levels, improves mood, strengthens your immune system, reduces stress, and improves sleep (“Walk your way to fitness,” 2021).

A brisk walk requires purposeful movements and good posture. Ideally while walking, you should:

  • Have your head up
  • Relax your neck, shoulders, and back
  • With a slight bend in elbows,  swing your arms freely
  • Straighten your back and stomach muscles slightly tightened
  • Roll your foot from head to toe, walking smoothly

Before you start your walking routine, it is vital to get the appropriate gear, walk in a safe environment, warm up, and cool down. Walking has many benefits, so grab a partner and simply walk!

Does the Keto Diet Work?

Amanda Benko | Intern UAB School of Education – CHHS

The Ketogenic diet, typically known as the Keto diet, is a high-fat, sufficient-protein, and very minimal-carbohydrate diet. The diet works by imitating the metabolism of someone who is fasting to instigate the production of ketone (Zhu et al., 2022). Let us look at the advantages and disadvantages of the keto diet to determine whether the diet works or not.

The Keto diet works since it encompasses an individual restricting dietary carbohydrate, which is the body’s primary source of energy. This forces the body to break down stored fat and creates ketone bodies to use in place of carbohydrates (Dowis & Banga, 2021). The loss of body weight occurs since the body breaks down the body fats and also leads to loss of water weight when the carbohydrate diet is restricted. Nevertheless, the diet works only in the short term and is unreliable for long-term effects since restrictive diets such as keto can be challenging to keep up with. When a person discontinues the diet, there is a high probability that they may have an increase in weight. The Keto diet might also not work because when a person overeats fats and proteins, their total calories are beyond what the body can burn, meaning they may not lose weight.

The Keto diet can have health benefits for people who have chronic conditions such as hypertension, diabetes, kidney disease, and heart disease. The diet can also be beneficial for people with particularly hard-to-treat kinds of epilepsy. Dowis & Banga (2021) affirm that the diet can also help to prevent degenerative and chronic diseases. However, people with these medical conditions should seek consultation with a physician before taking part in the Keto diet.

The keto diet involves restricting carbohydrate intake and consuming more fats and adequate proteins. The diet helps to lose weight but only in the short term. The diet is also advantageous for individuals with chronic health diseases, but they need to participate in the diet with the consultation of a physician. People I know have had great results, but like any lifestyle change, research, and when in doubt, consult a physician.

Reducing the Risk of Heart Disease

By Reginia Dodson, Intern and UAB Community Health and Human Services Student

Heart disease is a leading cause of death in the United States, and the African American population is disproportionately affected by this disease. African Americans have a higher incidence of heart disease and a higher mortality rate from heart disease compared to other racial and ethnic groups. Several factors contribute to the higher incidence of heart disease among African Americans. These factors include socioeconomic status, lack of access to healthcare services, genetic predisposition, and lifestyle factors such as high blood pressure, high cholesterol, and obesity (American Heart Association, 2021).

Light exercise is any activity that raises your heart rate and breathing but still allows you to carry on a conversation. Examples of light exercise include walking, cycling, swimming, and gardening. These activities can have numerous benefits for heart health. For instance, light exercise can help to lower blood pressure, reduce inflammation, and improve insulin sensitivity (American Heart Association, 2018). All of these factors are key contributors to the development of heart disease.

Several studies have demonstrated that light exercise can reduce the risk of heart disease. One study, published in the Journal of the American Heart Association, followed 24,000 women for 11 years and found that those who engaged in light physical activity, such as walking, had a 30% lower risk of developing heart disease compared to those who were sedentary (Manson et al, 2002). Similarly, another study published in the British Journal of Sports Medicine found that light exercise, such as brisk walking, can significantly reduce the risk of developing heart disease (Kujala et al, 2003). Light exercise can also provide other health benefits, such as improving mental health, reducing the risk of obesity, and improving overall physical function (Mayo Clinic, 2018).

In conclusion, physical activity is an essential component of overall cardiovascular health, and light exercise can significantly reduce the risk of heart disease. Walking for as little as 30 minutes a day, five days a week, can reduce the risk of heart disease. Light to moderate physical activity for as little as two and a half hours per week can also provide health benefits. By incorporating light exercise into our daily routines, we can reduce our risk of heart disease and improve overall health outcomes.

Planting Female Trees in Green Spaces can Prevent Asthma

By Reginia Dodson, Intern and UAB Community Health and Human Services Student

 Asthma is a chronic respiratory disease that affects millions of people worldwide, and the African American community is disproportionately affected by this condition. According to the Centers for Disease Control and Prevention (CDC), African Americans are three times more likely to die from asthma-related causes than non-Hispanic whites (2021). Environmental factors contribute to the higher incidence of asthma in African American communities. Poor air quality, exposure to pollutants, and lack of access to green spaces are all associated with an increased risk of asthma (National Heart, Lung, and Blood Institute, 2021).  

One potential solution to reducing the incidence of asthma in African American communities is the planting of female trees in green spaces. Female trees are known for their ability to capture and filter pollutants from the air, such as nitrogen dioxide and ozone, which are known asthma triggers. Studies have shown that planting female trees in urban areas can significantly improve air quality and reduce the risk of asthma (Donovan et al., 2013). Female trees produce less pollen than male trees, making them more suitable for individuals with pollen allergies, which can trigger asthma symptoms (U.S. Department of Agriculture, 2021).

In addition to improving air quality, green spaces have been shown to positively impact overall health and well-being. Access to green spaces can improve mental health, reduce stress and anxiety, and promote physical activity, all of which contribute to improve respiratory health (Kondo et al., 2018).  Community-based programs that encourage the planting of female trees in green spaces can effectively reduce the incidence of asthma in African American communities. These programs can be tailored to meet the specific needs of the community and provide education on the benefits of green spaces and the importance of respiratory health.

In conclusion, asthma is a significant health issue that disproportionately affects African American communities. Planting female trees in green spaces can improve air quality and reduce the risk of asthma, promoting overall health and well-being. Community-based programs that promote the planting of female trees in green spaces effectively reduce the incidence of asthma and improve respiratory health outcomes in African American communities.
