Abdominal cramps are common in men and can be caused by an underlying medical condition or an acute medical problem. If stomach cramps last more than a few days, even if they are mild, seeking medical help is necessary. Most mild causes of abdominal cramps in men usually go away on their own with home treatment without the need to see a doctor. Severe causes often require medical attention. More serious causes of abdominal cramps may include: Appendicitis Appendicitis is a painful condition caused by an inflamed appendix, an organ located in the lower right part of the abdomen. Other symptoms of the condition include: Loss of appetite; Vomiting; High fever Appendectomy (surgical removal) is required before perforation (rupture of the appendix) leading to potentially life-threatening complications. Intestinal obstruction An intestinal obstruction occurs when there is a blockage of an intestinal tract in the small intestine or in the large intestine. This can interfere with digestion and absorption of nutrients. Inflammatory bowel diseases, hernias and tumors are possible causes of the condition. Along with the strong cramps in the abdomen, the following can also occur: Dehydration; Abdominal swelling; Lack of appetite; Inability to have a bowel movement Bowel obstruction is a serious condition that requires surgery to correct the blocked bowel. Gallstones With gallstones, the spasms often spread to the right side of the abdomen. The pain is usually severe, can last for hours, and may radiate to the back. Gallbladder surgery is the best treatment for this condition. Kidney stones Kidney stones are also characterized by severe and prolonged pain. The pain can also spread to the groin. Other symptoms include painful urination and nausea. This condition may require emergency medical attention to initiate treatment to help pass the kidney stones. Viral and bacterial infections Rotaviruses and food poisoning from spoiled food can cause abdominal cramps along with severe diarrhea and vomiting. Most cases improve after a day or two, but if the condition worsens, a visit to the doctor is necessary. Bibliography: National Health Service (NHS).
