Hello Sir, Firstly I would like to confirm if your brother has duodenal ulcer and not gastric ulcer; duodenal ulcers being more common. Considering he has duodenal ulcer, I would suggest that the things he is avoiding are perfect. But ask him to have food are regular intervals. His diet should be rich in milk as milk will help relieve his symptoms. I would suggest one home remedy: 6 gms of leaves and flowers of pomegranate tree should be ground in water and given to the patient to drink.
