Hello respected Doctors Good afternoon My name is Ishani. I am 35 yrs old unmarried female. My weight has always been 45 kgs and I am 5.3 in height. But since last week I am drastically gaining weight. I feel very weak. My weight is now 55. My appetite is ok. But sudden weight gain with weakness... Too much of weight gain is not good as there are so many complications arising out of it related to diabetes and heart. My thyroid function test is normal and bp normal. I follow a vegan diet. I don't have PCOS or PCOD that has been ruled out by usg and fsh. Regards
