The actual cause of hemorrhoids is not known. But hemorrhoids are common in patients with spinal-cord injuries, constipation, chronic diarrhea, poor bathroom habits, postponing bowel movements, and a poor-fiber diet. Hemorrhoid is not caused by smoking. Hemorrhoids tend to get worse over time, and it should be treated as soon as it is diagnosed. Several surgical and non-surgical techniques are used to treat hemorrhoids. At time stage you must go to a surgeon. He will better guide you about further action. There are some preventive measures which I can tell you over here. Those are 1. Include fiber in your diet. Food sources of fiber include split peas, lentils, black beans, lima beans, and baked beans, whole grains, vegetables and fruits such as raspberries, pears, and apples 2. Drink 4 – 5 liters of water daily 3. Avoid weight lifting 4. Avoid straining while defecating 5. Avoid coughing 6. Syrup lactulose 2 teaspoonful per oral at bed time if you have constipation 7. Investigation – Hb% Remember hemorrhoid is a curable disease. Consult your surgeon and get done operation early. Surgery is the only cure. Smoking has no relation with hemorrhoid. But smoking causes other problems like high blood pressure, lung cancer, and peptic ulcer disease etc. If you are willing to quit smoking then it is good for your health. Thanks
