Difficulty digesting certain fruits, pulses and vegetables, with bloating and dizziness, usually points to food intolerance or an IBS-type sensitivity. This isn't something a tubectomy typically causes directly.
Next Steps
Keep a simple food diary to confirm exactly which foods trigger it, and eat smaller portions of pulses and raw vegetables for now. Since you've reacted badly to medicines before, mention this clearly to your physician before trying anything new.
Health Tips
See a physician or gastroenterologist if the bloating or dizziness keeps happening or feels severe, so other causes can be ruled out.
