Abdominal Discomfort

Medically Reviewed By William C. Lloyd III, MD, FACS

What is abdominal discomfort?

Abdominal discomfort is an unpleasant or painful sensation in the belly. The digestive tract occupies a large portion of the abdomen and is often the source of abdominal discomfort, although abdominal discomfort can also be due to conditions of the body wall, skin, blood vessels, or urinary tract. Occasionally, conditions of the reproductive organs or the chest can create abdominal discomfort.

Generalized pain may be due to gas, indigestion, or an infection. When more severe, especially if constipation is also occurring, an intestinal obstruction may be present. Disease of or damage to an organ such as the appendix, gall bladder, spleen, or stomach might be the source when pain is more localized. The area may be tender to the touch or, in the case of a ruptured appendix or similar problem, the pain may be severe and the whole abdomen might be rigid.

Pain can also be intense with conditions such as gallstones or kidney stones. When stones are causing the symptoms, the pain often occurs in waves, with a rapid onset of pain followed by some level of resolution. Pain that is more cramp-like in quality may be due to gas or indigestion. In women, abdominal discomfort may be due to menstrual cramps, endometriosis, or pelvic inflammatory disease.

Persistent, severe, or worsening pain, or pain accompanied by other serious symptoms tends to be the most worrisome.

Abdominal discomfort can be related to a variety of conditions ranging from minor to serious. Seek immediate medical care (call 911) for severe pain that comes on suddenly, the inability to have bowel movements, bloody stool, vomiting blood, abdominal rigidity, breathing difficulties, or pain in the neck, chest, shoulders, or between the shoulders. You should also seek immediate care if you have cancer or if you might be pregnant and have the sudden onset of abdominal pain or vaginal bleeding.

If your abdominal discomfort is persistent or causes you concern, seek prompt medical care, particularly if you have pain that is worsening instead of improving. Do not eat or drink anything until your symptoms are evaluated. If you have bladder symptoms, fever, decreased appetite, or unexplained weight loss, you should also seek prompt medical care.

What causes abdominal discomfort?

Abdominal discomfort often originates in the digestive tract. It can also be due to disorders of the circulatory system, urinary tract, reproductive system, respiratory system, or the body wall.

Digestive causes of abdominal discomfort

Abdominal discomfort may be caused by digestive conditions including:

Other causes of abdominal discomfort

Abdominal discomfort can also be caused by conditions involving other body systems including:

  • Abdominal or hiatal hernia (weakening in the abdominal wall or diaphragm, through which internal organs can pass)
  • Cancer of an abdominal or pelvic organ
  • Endometriosis (condition where tissues resembling the uterine lining grow in other areas of the body)
  • Kidney stones
  • Menstrual cramps
  • Pelvic inflammatory disease (PID; infection of a woman’s reproductive organs)
  • Pleurisy (inflammation of the lining around the lungs)
  • Pneumonia
  • Shingles (painful, blistering rash, often forming a stripe, that results from a reactivation of the varicella-zoster, or chicken pox, virus)
  • Urinary tract infection

Serious or life-threatening causes of abdominal discomfort

In some cases, abdominal discomfort may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include:

  • Abdominal abscess
  • Aneurysm of the abdominal aorta (life-threatening bulging and weakening of the wall of the abdominal aorta that can burst and cause severe hemorrhage)
  • Appendicitis
  • Bowel obstruction or perforation
  • Chemical or heavy metal poisoning
  • Colonic volvulus (twisting of the colon) or intussusception (telescoping of the intestines into themselves)
  • Ectopic pregnancy (life-threatening pregnancy growing outside the uterus)
  • Intestinal ischemia (loss of blood supply to the intestines leading to death of intestinal tissue)
  • Myocardial infarction (heart attack)
  • Ovarian or testicular torsion (twisting of the ovary or spermatic cord)
  • Peritonitis (infection of the lining that surrounds the abdomen)
  • Significant abdominal, pelvic or testicular trauma

Questions for diagnosing the cause of abdominal discomfort

To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your abdominal discomfort including:

  • When did you first notice your abdominal discomfort?
  • Where do you feel the discomfort?
  • How would you describe your discomfort?
  • Does anything make it go away or make it worse?
  • Have you had pain like this before?
  • Do you have any other symptoms?
  • What medications are you taking?
  • Is there any possibility you might be pregnant?

What are the potential complications of abdominal discomfort?

Because abdominal discomfort can be due to serious diseases, failure to seek treatment can result in serious complications and permanent damage. Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:

  • Bowel infarction (severe injury to an area of the bowel due to decreased blood supply)
  • Infertility
  • Internal hemorrhage
  • Intestinal obstruction and rupture of the intestinal wall
  • Organ failure or dysfunction
  • Ruptured appendix
  • Spread of cancer
  • Spread of infection
