hi dear kershawm,
welcome to hcm.
Kindly specify if your husband has any pain abdomen. This would help in ruling out some specific organisms causing the symptomatology.
Kindly give him plenty of fluids orally. I would like to advice for ORS
(Please purchase 4-6 sachets from the pharmacy. Use 1 sachet in 1 litre of water. Kindly make him drink the first litre in 4hrs followed by the second to be finished in next 6hours and so.)
U can give him Cap. Nutrolin B Plus twice daily for 5days. Kindly avoid spicy, oily, junk food & non vegetarian food. Use only well cooked items avoid any uncooked foods.
If the symptoms do persist, kindly get a stool examination done. Kindly check his HbA1c
level as well in the lab.
Hope this will help for a speedy recovery.
