Health Issues for Overweight & Obesity

The alarming range between 25-29.9 and 30 or above is the ultimate indication of overweight and obesity, that calls for taking immediate healthier measures. It has huge repercussions for overall health and wellness, including a high risk of chronic conditions such as diabetes, cardiovascular diseases, and certain cancers.

Here are some disease that comes with obesity and overweight: 

• Type 2 diabetes : Being overweight or obese makes it more likely to get type 2 diabetes. Extra weight makes your body not respond well to insulin, which controls your blood sugar. High blood sugar over time can lead to heart disease, stroke, kidney issues, eye problems, nerve damage, and more health troubles.
• Hypertension:  Overweight bodies tend to make the heart pump harder than it usually requires that leads to increased blood pressure, eventually hypertension occurs. 
•  CVD: Cardiovascular disease includes problems with your heart and blood vessels, like heart attacks and strokes. Extra weight can put more strain on your heart and blood vessels.
• High LDL cholesterol (“bad” cholesterol) & High triglycerides: Carrying extra weight can raise the levels of bad fats in your blood, which can clog your arteries and lead to heart problems.
• High blood glucose (sugar): Extra weight can make it harder for your body to control blood sugar levels, leading to high blood sugar, which is a risk factor for diabetes.
• Gallbladder disease: Obesity increases the risk of gallstone formation, particularly in women with higher BMI. Gallstones, mostly made of cholesterol, form due to imbalances in bile substances. Maintaining a healthy weight is crucial to prevent gallstone development.
• Certain cancer: Cancer is usually caused in association with other diseases and health conditions, however, obesity can increase your chances for about 13 types of cancers, including breast, colon, gallbladder, pancreatic, kidney, and prostate cancer, as well as cancer of the uterus, cervix, endometrium, and ovaries. A one population-based Trusted Source study in 2012 says, approximately  28,000 new cases of cancer in men and 72,000 in women were associated with being overweight or having obesity in the United States.
• Liver disease : Obesity is connected to a range of liver issues known as nonalcoholic fatty liver disease (NAFLD). The severity of liver damage tends to increase with higher BMI levels, leading to liver damages. 
• Depression : Obesity often brings on depression, many can face discrimination because of their size, it also decreases productivity and feelings of depression. This could be due to factors like reduced energy levels, physical discomfort, and the psychological impact of societal stigma. Which can lead to feelings of sadness or low self-esteem over time.
• Sleep apnea: Overweight can lead to blockage in your upper airway, such as in the throat or nose, thus your breathing patterns can become irregular. In some cases, this blockage may even cause you to stop breathing altogether for short periods of time. This interruption in breathing, known as sleep apnea, can occur repeatedly throughout the night, leading to disrupted sleep and potentially serious health consequences.

How to improve from overweight and obesity?

The first step would be to have thoughtful dietary control, and being conscious that anything goes into the body has an impact on yourself. Changing up your lifestyle and food habits helps, start off by getting enough fiber in your food, as it helps with digestion and makes you feel full, which restraints you from eating again and again.

Try intermittent fasting, which involves short periods of not eating, to give your digestion a boost. Additionally, to keep your gut bacteria happy,  add some probiotic and prebiotic foods to your meals. Go for healthier food options and cut back on sugary, fatty, and processed items. Make sure to get more physical activity, as it’s great for your body and mind.

Take care of any health issues with the right medical advice and lifestyle tweaks. And don’t forget to cut down on stress with some relaxation techniques, and self-care. These changes can make a big difference in your weight and overall health.

Medications Guideline

The following drugs mentioned here are the FDA (The United States Food and Drug Administration is a federal agency of the Department of Health and Human Services) approved prescribed medications suggested for weight loss. The FDA has sanctioned five of these medications—Orlistat (Xenical, Alli), Phentermine-Topiramate (Qsymia), Naltrexone-Bupropion (Contrave), Liraglutide (Saxenda), and Semaglutide (Wegovy)—for long-term use.

Note that one may continue these medications as long as these are effective and not experiencing any serious side effects. Some appetite-suppressing weight management drugs are FDA-approved for short-term use only, up to 12 weeks. 

Therefore, do not consume these unless your doctors have prescribed you to. 

How BMI Reflects Your Health

While BMI tells you the balance charters of your body, it fails to put a consideration of individual body type and condition, which often makes false body assessment to an extent. Here’s the factors that needs to be taken account for while considering health balance of one’s body, 

• Muscle mass: The body weight contains muscle mass along with the fat, thus it makes one appear to be overweight when in fact the fat adds significantly to the overall weight. 
• Bone density: People with higher bone density will naturally have added weight as their bone structure is heavier, thus the accuracy of weight is compromised. 
• Body composition: As one ages, the body composition changes with the chance of having more visceral fat and less of muscle mass. Both of these have a significant impact on one being overweight, whereas the weight may be a healthy one. 
• Ethnicity: People from different ethnicities have unique body compositions, according to their ancestry which includes variations of muscularity, bone mass, even body fat.
