My weight suddenly increases this month. I don't know if this is a serious problem or not. It was stable before this month but suddenly increases. I don't know how. I also feel very low sometimes. I am not taking any prescription right now and I don't know if it is a serious problem or not. Should I consult someone or it will be okay? please help me. Need your urgent help. Thank you please revert back soon. Waiting for your reply.
