Hello, 1. As there is a history of eating cement/whitewash thus probably it points towards iron deficiency anemia but without being able to take a proper history and examine you directly, I m of the following opinion: 1. Although you have mentioned the weight but not about your Height which will help assesses your BMI [body mass index]. 2. Any history of Allergy, acid reflux or malabsorption can result in non-absorbing of nutrients and not gaining weight. 3. Take an opinion of your primary care doctor who after a thorough examination can refer you either to a Medicine Specialist or a Haematologist for CBC [complete blood culture] and stool test and only thereafter specific management can be started, till then: i. Encourage outdoor games and exercises like running, swimming, Yogasanas, Surya-namaskar. ii. Take protein rich diet (legumes sprouted pulses/cereals, milk with protein powder (which are required for manufacturing of antibodies). iii. Take vitamin A,B,C,E in the diet which helps in strengthening the immune system. iv. self-expressed juice of white onion 6ml with honey in the morning and good sleep after meals 1. first deworming is essential: make powder of raw mango seed and take 250mg with yogurt or water empty stomach in morning for three days (AVOID: cucumber, long cucumber, raw fruits, potato, meat, sugar, sour foods, milk, jaggery, clarified butter for 15 days) and give walnut, pineapple, and peach. 2.
