What Causes Lower Abdominal Pain in Men? 26 Possible Causes

1. Prostatitis
   1. Inflammation of the prostate gland can cause aches and pains in the lower abdomen and upper thighs.
   2. Prostatitis affects around 90% of men who suffer from persistent pelvic pain.
2. Testicular torsion (twisted testicle)
   1. A twisted testicle can cause intense discomfort in the genital area and lower abdomen and quickly turn into a medical emergency.
   2. The pain usually comes on unexpectedly and may cause the scrotum to enlarge. The discomfort may spread from the groin to the lower abdomen.
   3. Men who experience acute, unexpected testicular pain should consult a doctor as soon as possible.
3. Inguinal hernia
   1. Although women can be affected by inguinal hernias, they are more common in men and can cause intermittent lower abdominal pain.
   2. A hernia occurs when a portion of the small intestine bulges through the lower abdominal wall, causing a painful or sensitive lump on one or both sides of the groin.
   3. Lifting heavy objects, coughing, sneezing. or exercising can aggravate the discomfort.
   4. Surgery is the only option to treat the hernia and prevent it from causing stomach pain.

   1. Bacteria that enter the kidney and cause an infection can cause severe stomach discomfort around the flanks, radiating to the back and the umbilical area.
   2. Not drinking enough water and subsequent dehydration can increase the risk of kidney problems.
5. Kidney stones
   1. Kidney stones passing through the urinary tract can cause severe lower abdominal pain as well as pain in the lower back, groin, or testicle.
   2. The pain may be severe enough to cause nausea and vomiting.
6. Urinary tract infection (UTI)
   1. A UTI can cause lower left abdominal pain or lower right abdominal pain, which increases with urination.
   2. Urinary infections can be caused by kidney disease, an enlarged prostate, or catheter use and may spread into the kidneys causing intense discomfort.
   3. Antibiotics are usually required to treat UTIs and prevent complications.
7. Bladder inflammation
   1. Although bladder infections and urinary infections are more common in women, men can also have pain below the umbilical button as a result of bladder inflammation.
   2. Doctors advise men who complain of lower abdominal pain to be evaluated for enlarged prostate as well as bladder issues.

   4. Appendicitis can rapidly escalate into a medical emergency. If you experience symptoms of an inflamed appendix, contact your doctor immediately.
10. Trapped gas
    1. Gas accumulation in the intestines can cause severe stomach cramps. Fiber-rich and carbohydrate-rich diets are two of the most common causes.
    2. Gas trapped on the left side of the colon can cause severe lower left stomach discomfort or even severe left-sided chest pain.
    3. Trapped gas on the right side of the colon can cause severe stomach discomfort that feels like appendicitis.
