Not just okra, any vegetable containing fibre helps with regular bowel movements.
Next Steps
Consider adding other fibre containing vegetables in your diet like green peas, broccoli, carrots, spinach, beetroot etc.
If your constipation is new, or if there is any recent change in your bowel habits, it is better to consult a doctor.
