Long Term Effects of Obesity on Your Health

Obesity is quickly becoming the most consequential health epidemic in the United States. Obesity is defined as the accumulation of body fat to the point where it becomes detrimental to your health. The effects of obesity on your health are substantial. As an individual’s weight increases, so do the risks of developing significant medical issues that can shorten a person’s life expectancy. The sad reality is that the disease of obesity directly or indirectly affects every part of our body.

As bariatric professionals, we measure obesity based on your body mass index (BMI). BMI is calculated based on your height and weight. A BMI of 25 to 30 is considered overweight, 30 to 35 is obese, and 35+ is considered morbidly obese.

When a patient’s BMI exceeds 30, they are at an increased risk of developing harmful health conditions. These conditions include arthritis, cancers, type 2 diabetes, depression, high blood pressure, high cholesterol, and obstructive sleep apnea.

Effects of Obesity on Your Health

Obesity is a gateway to all the above-mentioned conditions, leading to a reduced quality of life. The longer you are impacted by obesity, the more these conditions can affect your health. Likewise, the higher your BMI, the more complex these conditions are to control and the more severe they tend to be, potentially leading to coronary artery disease, heart attacks, strokes, and even death.

Treating obesity can add more than ten years to your life expectancy and reduce or cure all of the weight-related conditions associated with your weight. Therefore, it is critical to recognize obesity as a chronic disease and understand how weight gain affects your body.

Effects of Obesity: Arthritis

One pound of weight is equivalent to four pounds of pressure on your joints. As you lose weight, you will experience less pain in your joints due to less pressure. Likewise, your body will decrease cytokine production (inflammatory chemicals released by fat cells), leading to reduced aches and pains.

Effects of Obesity: Diabetes

Patients with excess weight are at a higher risk of being diagnosed with diabetes because they have more fat cells, increasing insulin resistance. This results in the body being incapable of regulating blood sugar levels, ultimately leading to type 2 diabetes. 

Effects of Obesity: Hypertension

Studies have found that a 5% increase in weight can lead to a 30% increase in the risk of hypertension. Many theories link obesity and hypertension due to the kidneys not functioning properly since the kidneys play a vital role in filtering the blood. The heavier a person is, the less effective their kidneys are at removing excess waste and liquid from the bloodstream, ultimately leading to the buildup of waste in the body. Similarly, when the kidneys do not function properly, this organ’s hormones designed to regulate blood pressure are not secreted.

Effects of Obesity: Heart Disease

Heart disease is commonly associated with cholesterol—a fat-like substance. The liver produces a sustainable amount of cholesterol to help the body encourage new cell and hormone growth. However, cholesterol is also consumed through fatty foods, resulting in plaque buildup in the artery walls over time. As expected, your diet greatly impacts your weight; therefore, overweight individuals are at a higher risk of developing heart disease.

Effects of Obesity: Obstructive Sleep Apnea

Having sleep apnea can prevent you from losing weight as well. Overweight individuals are more prone to sleep apnea because the soft tissue in their neck blocks the airway, preventing the individual from breathing. When you have obstructive sleep apnea, you never reach REM sleep and therefore never get a good night’s rest. As a result, you are always tired, which is shown to lead to unhealthy dietary choices. 


Obesity is associated with many of the leading causes of death, pain, and suffering in America and worldwide. We strongly recommend bariatric surgery as a treatment option for patients suffering from obesity.
