Alternatively, many drugs and illegal substances result in weight loss. Among them, depression may be the basic reason for weight loss in a large number of cases. In addition, bipolar disorder, especially in the manic and hypomanic phase, and eating disorders such as anorexia and bulimia, are strongly associated with a sudden weight loss. Abuse of addictive substances and even high stress are also potential culprits. Persistent vomiting or even nausea can mean that food intake is too low to maintain weight. People are likely to mention doctors serious GI problems. This gives doctors the opportunity to check infections or evaluate the functioning of GI for problems such as obstaclesky.
