Bloating and stomach pain, even after past ulcers with high homocysteine, can be due to incomplete healing, sensitive digestion, or a vitamin deficiency affecting the gut. Eat simple home food, avoid spicy and oily items, have meals on time, and stay hydrated to support digestion. Include foods rich in vitamins such as B12 and folate, manage stress, and maintain a regular routine to improve symptoms. If discomfort continues or worsens, consult a doctor to check levels and guide proper treatment.
