I m too skinny why!!! Can anybody solve this problem

At 18 you have probably finished your growth spurts. 38 kilos is only about 84 lbs. which is very skinny. Have you had a physical with a doctor to see if there is an underlying medical condition? Unfortunately if you are trying to attract girls, and I hope you mean women of your age, then you are at a disadvantage. You are going to have to put some beef on your bones, there is not much you can do with your height now. You will also have to figure out how to compensate for your lack of physical attractiveness. This sounds cruel, but is unfortunately a reality with women. First go to the doctor to check your health, second take up some weight training to beef your muscles, and third figure a way of making some money. Lots of money can sometimes compensate for mediocre looks.

which part of india are u from.. i am a medical student.. people who remain thin have more of brown adipose tissue (brown fat), which wont help u to become fat.. ur height is atleast fine(wats ur parents ht), but ur weight is less for age.. u can consult an endocrinologist abt it.. good food, at regular times, with proper sleep n exercise is a must.. missin any of these, will affect u.. also seems ur interested in legit wealth earning.. do ask help if needed.. r regards

I guess you are skinny because you have a fast metabolism. Other reasons could be because a person can have an underlying condition, like hypothyroidism, cancer, or cachexia syndrome. If you were able to undergo a stomach surgery, it could be because of dumping syndrome. Those are usually the reasons.
