I am Dr. Ajay Nihalani, Psychiatrist. Today I will talk about depression. One needs to understand the symptoms of depression. Not everyone will end up having symptoms. It affects your sleep. Their pleasure gets affected. Appetite goes down. Their relationship gets affected. We end up having weight loss. They tend to get weight. They have concentration problems. They suffer from body pain. Their speed of thoughts becomes slow. They feel guilty about everything like if their families are suffering, job issues. They start getting the thoughts of suicide. It is a very common illness. When someone is in depression, their symptoms last for days and weeks. The cause could be genetic, stress, strain in their life. Deficiency of neurochemical in the brain. Lifestyle changes, yoga, exercise are important. But if depression is more than mild, you should take the help of the Dr.
