Peritonitis is an inflammation of the peritoneum, the thin membrane that lines the abdominal wall and covers the organs inside. It is caused by a bacterial or fungal infection.

There are two major types of peritonitis. Primary peritonitis happens when an infection spreads from the blood and lymph nodes to the peritoneum. This type of peritonitis is rare -- less than 1% of all cases of peritonitis.

The more common type of peritonitis, called secondary peritonitis, happens when the infection comes into the peritoneum through a perforation in the abdominal wall.

Both cases of peritonitis are very serious and can be life threatening if not treated quickly.

Signs and Symptoms

The signs and symptoms of peritonitis include:

  • Swelling and tenderness in the abdomen with pain ranging from dull aches to severe, sharp pain
  • Fever and chills
  • Loss of appetite
  • Thirst
  • Nausea and vomiting
  • Less urine
  • Not being able to pass gas or stool

Causes

Primary peritonitis is usually caused by liver disease. Fluid builds up in the abdomen, creating an environment for bacteria to grow.

Secondary peritonitis is caused by other conditions that allow bacteria or fungus to come into the peritoneum from a hole or tear in the abdominal wall. Tears can be caused by pancreatitis, a ruptured appendix, stomach ulcer, Crohn's disease, or diverticulitis. Peritoneal dialysis, which uses the blood vessels in the abdomen to filter waste from your blood when your kidneys can’t, also may cause peritonitis.

Risk Factors

The following factors may increase the risk for primary peritonitis:

  • Liver disease (cirrhosis)
  • Fluid in the abdomen
  • Weakened immune system
  • Pelvic inflammatory disease
  • Risk factors for secondary peritonitis include:
  • Appendicitis (inflammation of the appendix)
  • Stomach ulcers
  • Torn or twisted intestine
  • Pancreatitis
  • Inflammatory bowel disease, such as Crohn's disease or ulcerative colitis
  • Injury caused by an operation
  • Peritoneal dialysis
  • Trauma

Diagnosis

Peritonitis is an emergency and can be life threatening, so the doctor will first do a physical examination to see whether you need surgery to fix the underlying problem. The doctor will feel and press your abdomen to find any swelling and tenderness. He will also look for signs that fluid has collected in the area. The doctor may listen to bowel sounds and check for difficulty breathing, low blood pressure, and signs of dehydration.

The following procedures also may be performed:

  • Blood tests -- to see if there is bacteria in your blood
  • Samples of fluid from the abdomen -- identifies the bacteria causing the infection
  • CT scan -- identifies fluid in the abdomen, or an infected organ
  • X-rays -- spots air in the abdomen, which means that an organ may be torn or perforated

Preventive Care

To prevent serious complications from peritonitis, get medical help as soon as symptoms appear. If you are getting peritoneal dialysis, you can help avoid peritonitis by cleaning the area around the catheter with antiseptic and washing your hands before touching the catheter.

Treatment

If you have symptoms of peritonitis, get immediate emergency medical help. You will likely need to stay in the hospital for treatment. You may need surgery to get rid of the source of infection, such as an inflamed appendix, or to repair a tear in the abdominal wall. You will get antibiotics to control infection. You may use complementary therapies along with conventional medicine when you are recovering from peritonitis.

Medications

Your doctor will prescribe antibiotics to kill bacteria and keep the infection from spreading. What is prescribed depends on the type of peritonitis and what's causing the condition.

Surgery and Other Procedures

People with peritonitis often need surgery to remove infected tissue and fix damaged organs.

Nutrition and Dietary Supplements

Peritonitis is a medical emergency and should be treated by a medical doctor. Do not try to treat peritonitis with herbs or supplements.

When you are recovering, a comprehensive treatment plan may include complementary and alternative therapies. Ask your team of health care providers how to include these therapies in your overall treatment plan. Always tell your health care provider about the herbs and supplements you are using or considering using.

These good nutrition habits may help you recover from any serious illness:

  • Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell peppers).
  • Eat foods high in B-vitamins and calcium, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
  • Avoid refined foods, such as white breads, pastas, and especially sugar.
  • Eat fewer red meats and more lean meats, cold-water fish, tofu, or beans for protein.
  • Use healthy oils in foods, such as olive oil or vegetable oil.
  • Avoid caffeine, alcohol, and tobacco.
  • Drink 6 - 8 glasses of filtered water daily.
  • Ask your doctor about taking a multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals such as magnesium, calcium, zinc, and selenium.
  • Probiotic supplement (containing Lactobacillus acidophilus among other species), 5 - 10 billion CFUs (colony forming units) a day, for gastrointestinal and immune health. Probiotics can help when you are taking antibiotics, because they can help restore the balance of "good" bacteria in the intestines. People with autoimmune diseases, such as lupus or rheumatoid arthritis, or people with weakened immune systems should ask their doctor before taking probiotics.

Herbs

You may use herbs when you are recovering from peritonitis, but you should never use herbs to treat peritonitis. Ask your doctor before taking any herbs or supplements while you are recovering.

Homeopathy

Homeopathy may be used when you are recovering from peritonitis, but do not use homeopathy alone to treat peritonitis. Peritonitis is a medical emergency. Few studies have examined the effectiveness of specific homeopathic remedies. A professional homeopath, however, may recommend one or more of the following treatments for peritonitis based on their knowledge and clinical experience. Before prescribing a remedy, homeopaths take into account a person’s constitutional type -- your physical, emotional, and intellectual makeup. An experienced homeopath assesses all of these factors when determining the right remedy.

  • Belladonna -- for people who are hypersensitive to touch, have sudden attacks of pain that come and go, and have a high fever
  • Arsenicum album -- for people with a swollen abdomen, unquenchable thirst, extreme chills, and symptoms that worsen at night

Other Considerations

Prognosis and Complications

Complications from peritonitis can include:

  • Sepsis -- an infection throughout the blood and body that can cause shock, multiple organ failure, and death
  • Abnormal clotting of the blood, often due to widespread infection
  • Scar tissue in the peritoneum
  • Acute respiratory distress syndrome -- a severe infection of the lungs

The prognosis for peritonitis depends on the type of the condition. The outlook for people with secondary peritonitis tends to be poor, especially among the elderly, people with weakened immune systems, and those who have had symptoms for longer than 48 hours before treatment.

The long-term outlook for people with primary peritonitis due to liver disease also tends to be poor. However, the prognosis for primary peritonitis among children is usually very good after treatment with antibiotics.
