Hello,
This is Dr. Klarida Papaqako answering your question. Thank you for posting you concern on HCM.
If I'm understanding right your question, even if I have not exact weight and height to calculate if you are
underweight or not, you are telling me you are.
Some things that may work to help you gain weight are:
1) Eat a healthy diet, with a variety of food, especially the foods who have lots of
proteins (dairy, meats, eggs), Fibers (beans, fruits, vegetables) and drink plenty of water.
2) Eat 3-4 times a day, with snacks in between. Do it regularly, so your stomach will get used of the food slowly, and will accept larger amounts with time.
3) Exercise daily, start with 20 minutes at least 5 times a week, increasing gradually. Sometimes gym helps also, and there are exercises, who will help you gain muscular mas, that the gym instructors may recommend according your body stature.
4) Take multivitamins, according your age, who will help sometimes with the appetite.
If you have any other questions, please feel free to ask.
Regards.
