Read MoreWhipple's Disease: Symptoms, Causes, Diagnosis, and Treatment
Medically reviewed by Jerome Albert Ecker | MD, Assistant Professor of Medicine, Duke University - Durham, NC on November 23rd, 2023.
Key Takeaways
- Tropheryma whipplei primarily strikes middle-aged Caucasian men (over 90% of cases), though the exact transmission route remains unknown and person-to-person spread doesn't occur.
- Classic symptoms include chronic foul-smelling diarrhea, dramatic weight loss (often 20+ pounds), and distinctive brownish skin pigmentation, particularly around sun-exposed areas.
- Diagnosis requires small bowel biopsy showing characteristic PAS-positive macrophages filled with bacterial remnants—standard stool cultures won't detect this organism.
- Treatment begins with IV ceftriaxone or penicillin for 2 weeks, followed by oral trimethoprim-sulfamethoxazole for 12-24 months to prevent relapse.
- Without treatment, the infection is universally fatal, but proper antibiotic therapy achieves cure rates above 90% when completed as prescribed.
Whipple's disease is a rare bacterial infection that primarily affects the digestive system, particularly the small intestine. However, it can also cause problems in other parts of the body, such as the heart, joints, lungs, eyes, and immune system. If left untreated, Whipple's disease can be life-threatening.
Symptoms of Whipple's Disease
The symptoms of Whipple's disease can vary from person to person, but the most common signs include:
Abdominal pain
Diarrhea (foul-smelling)
Malabsorption
Weight loss
Dark spots on the skin
Joint pain
In some cases, Whipple's disease can also affect the nervous system, leading to symptoms such as:
Loss of muscle control
Confusion and memory loss
Seizures
Vision problems
Causes of Whipple's Disease
Whipple's disease is caused by a type of bacteria called Tropheryma whipplei (T. whipplei). Scientists are not entirely sure how the bacteria enter the body, but they suspect it may be part of some people's normal bacterial mix or that it may enter through the mouth. There is no evidence to suggest that Whipple's disease can be transmitted from person to person.
Research has shown that many people with Whipple's disease work in occupations that involve close contact with soil, such as farming or construction. Additionally, some individuals with the condition may have a compromised immune system or a genetic predisposition to the disease.
Diagnosing Whipple's Disease
If your doctor suspects that you may have Whipple's disease, they will begin by reviewing your medical history and performing a physical examination to check for abdominal tenderness or dark spots on your skin. They may also order a blood test to check for nutrient deficiencies or to detect the presence of T. whipplei DNA.
To confirm the diagnosis, your doctor will likely recommend an upper gastrointestinal endoscopy. During this procedure, a flexible tube with a camera attached is inserted through your mouth and into your stomach and small intestine. This allows your doctor to examine the lining of your digestive tract and take a tissue sample (biopsy) to test for the presence of T. whipplei bacteria.
Treating Whipple's Disease
If you are diagnosed with Whipple's disease, your doctor will prescribe antibiotics to eliminate the bacteria. Initially, the antibiotics will be administered intravenously (through an IV) to ensure that the medication reaches all affected areas of your body. Your doctor may also recommend fluids to prevent dehydration and supplements to address any nutrient deficiencies.
Most people with Whipple's disease begin to feel better within a couple of weeks of starting treatment. However, it can take up to two years for the small intestine to fully recover. During this time, you will need to continue taking antibiotics and supplements as directed by your doctor.
If Whipple's disease has affected your nervous system, your doctor may prescribe a combination of antibiotics, steroids, and other medications to manage your specific symptoms.
It is important to note that Whipple's disease can recur, so regular follow-up appointments with your doctor are essential to monitor your health and promptly treat any recurrences.

The Bottom Line
This rare but deadly bacterial infection requires specialized testing and prolonged antibiotic treatment, but responds excellently when caught early. The combination of chronic diarrhea, weight loss, and joint pain in middle-aged men should raise immediate suspicion. If you're experiencing these concerning symptoms, Doctronic can help connect you with appropriate specialists for rapid evaluation.
