Typical neurovegetative symptoms of depression are loss of apetite and loss of sleep. Loss of appetite will result in weight loss in a depressed person along with other symptoms of depression. But in some people with depression, atypical neurovegetative symptoms of increased appetite and increased sleep are seen.
Hence some depressed people gain weight and may become obese. Some will go on gaining weight without understanding that this may be due to their masked depression and negative thoughts, stresses, and their conflicting issues.
Depression may be implicated as possibly triggering a craving for carbohydrates. Some say, ‘when i am depressed, I eat.” This suggests that eating may reduce the gloomy thoughts associated with depression in much the same way as cigarette smoking or alcohol consumption. Some clinical studies show that already obese subjects were 5 times more likely to gain weight while depressed than were the non-obese.
Symptoms of weight gain were significantly associated with obesity. Both overeating and oversleeping were more common among obese.
Hence obesity should not be taken lightly. It may be sign of depression.
