Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
For increasing apetite and weight gain there is no need for taking tryptomer
. I will advise you to take syrup cyproheptadine
before meals it will increase your apetite and for gaining weight if it is required take high fat and protein diet.
I hope I have answered your query and this will help you. If you have any further query I will be happy to answer that too. Remain in touch and get-well soon.
