Weight gain isn't the problem but the underlying issues that may hamper in normal process. You should be knowing that there is a genetic component of metabolism as well, the reason that not the same diet effect everyone in the same way. Its best to get a consult with a nutritionist and have your BMI calculated yourself. Its less likely to be a disease. But possibilities can be ruled out.
