Hello dear!! This is very common problem. Few days back my father in law also faced the same issue. We have also done with all tests. Everything is normal. His hb levels are little lower. As they grew older, they immune levels, resistance power gets slower. But don’t... See more worry. Stress free, healthy diet, light walking in fresh air, plenty of liquids could help him more better. Fever could be seasonal change, Infact sometimes they gain resistance Which more important at this age to fight with foreign particles. Stay strong.

Hello DearYou shouldn't take jackfruit as it aggravates jaudice, have lots of water, sugarcane juice if possible its very good. Have tomato juice with Himalayan salt. Have light food like daliya, khichdi, poha... See more , daal etc.Avoid oily and junk food,spicy food too. Try to sit in early morning sunlight atleast 10 min, have mausambi juice or lemon water.Follow your doctor's advice,you will be fine soon. Take care.
