hi,thanks for query.The symptoms of ulcer are heaviness in stomach after food,vomiting
at times,poor appetite
and blood in vomit or stool.In case of above symptoms medical examination by a doctor is must as it can lead to proper diagnosis.Normally treatment of gastric ulcer lasts upto 6-8 weeks,and without consulting doctor one should not take any medicines.Take good diet,less in oil and spices, avoid stress
and do regular exercise.
wishing you good health.
