Obesity and mood disorders are commonly related. I would strongly recommend that you see your primary care doctor
. There are many interactions between the two. If required, he or she may refer you to a psychiatrist
( a mood disorder specialist), who may be able to provide more assistance.
The psychological effects of obesity are varied. Some people have no effects. Some people suffer from severe depression
given their physical situation. I would recommend that you discuss this with your doctor. Regardless if they are related or not, either problems should be addressed.
Obesity can cause depression, but as you point out, depression can also cause obesity. In addition, there are some disease (such as endocrine disorders) which can cause both. These disorders are rare, but should be ruled out by discussion with your doctor. As it is often a vicious cycle, it is very hard to tease them apart and both should be treated.
Weight loss and exercise therapy are key for obesity treatment. In addition, some conditions which complicate obesity (like sleep apnea) should be addressed. Depression can also be treated with medicines as well as psychiatric therapy. For this, a psychiatrist may be helpful.
Talk to your doctor. There are many options and medicines available for your problems. Good luck!
