hi, if only constipation is your concern, fibre rich diet ( green leafy vegetables), drinking more fluid, regular exercise can help relieve constipation. Sitz bath improves the condition to a great extent. Also, if you are not satisfied with the above method, you can consume liquid paraffin or cremaffin syrup at night to ease defecation. Even with these, if your symptoms do not improve, surgery is another option available for hemarroids. Since you have a family history of colon cancer, you should get genetic studies done for FAP Gene. Another option is, regular monitoring with colonoscopy for screening of colon cancer. Prophylactic surgeries are available to prevent familial occurrence of colon cancers. Until complete workup is done, you don t have to panic.
