5 Potential But Unpopular Causes of Obesity
Obesity occurs not only as a result of excessive calorie-intake. It could also happen as an aftermath of an illness. It is upon these things that some people find themselves continuing to gain weight or failing to shed the extra pounds. See, despite efforts to get rid of unwanted pounds, proper dieting and exercise alone are not enough to guarantee the achievement of a desired weight.
Here’s a fact: Weight gain may be a result of various factors such as endocrine disorders, depression, lack of sleep, medications, and stress.
The endocrine system produces hormones and is responsible for various body processes and procedures – like metabolism. The amount of hormone this system produces affects the entire body. Endocrine disorders such as hypothyroidism are among the most common causes of weight gain. This disease, which may be diagnosed with simple blood test, is characterized by fatigue, weakness, dry skin, cold intolerance and depression.
Depression has also been scientifically proven to cause weight gain. This disorder may result from an imbalance of serotonin, a brain chemical that helps regulate mood and appetite. Serotonin imbalance leads to changes in appetite. This is the reason why people who are depressed either tend to eat a lot or none at all. Depression also manifests as isolation, the lack of motivation, feeling of hopelessness, loss of interest in activities previously enjoyed, as well as unexplained aches and pains. These symptoms affect the frequency and intensity of physical activity that may cause wight loss.
Being overweight may also be due to lack of sleep which occurs as a result of hormonal imbalances. When a person lacks sleep, he develops insulin resistance and eventually develops intense sugar cravings.
Medications such those for the treatment of diabetes as well as oral contraceptives contribute to weight gain. This is largely because these medications contain chemicals that trigger food cravings or promote fat build up.
Stress is another factor that contributes to weight gain. Stress increases the body’s cortisol, a hormone that is responsible for weight gain. The cortisol, also called the “stress hormone”, is also responsible for a person’s level of immunity, sensitivity to pain and homeostasis. As an added input, cortisol imbalances results in impaired cognitive performance, decreased bone density, and higher blood pressure among others.
