Hi, Thanks for writing to health care magic. That stomach upset you are experiencing could be because of several reasons. That may or may not be because of typhoid fever you had directly or indirectly. A physical examination is required to identify if it is because of that or some other cause. One common cause could be acid peptic disease. Consume a well balanced diet rich in proteins and vitamins. Consult your doctor for a physical examination to identify the cause of that stomach upset. Consume lots of fruits and vegetables and a soft diet. Continue to ask further queries as required. Hope this helps. Take care.
