Imagine that you went on vacation to a beautiful tropical country, or lived in one for a while. Suddenly, you start to feel very sick, and after a few days, your stomach aches start to subside. You feel weak and lose weight. You may have a condition called Tropical Sprue . Don't worry, we'll talk about it in detail.
What is Tropical Sprue?
Simply put, Tropical Sprue is a rare infection that affects your small intestine . What happens is that your body can't absorb the nutrients it needs properly. This is because some harmful bacteria enter your small intestine and damage it.
This disease is most common in people who live in or spend a lot of time in warm, tropical regions of the world, such as the Caribbean, South India, and Southeast Asia. It can start with a severe stomachache, then become a chronic condition, although it may subside a little.
Most importantly, if not treated properly, it can lead to serious complications like anemia and malnutrition.
Why is this called "tropical sprue"?
The name comes from a long time ago. In the 1600s, a Dutch doctor used the word "sprouw" to describe a persistent flatulence. About 200 years later, an English doctor studying stomach problems in warm countries picked up the word. "Sprouw" later became "sprue." Sometimes doctors also refer to celiac disease as "non-tropical sprue" or "celiac sprue."
What are the symptoms of Tropical Sprue?
At first, the symptoms of tropical sprue may feel like traveler's diarrhea , but a little more severe. Traveler's diarrhea often goes away on its own in a few days, but the symptoms of tropical sprue do not. They persist, and may even get worse. Other symptoms include:
- Stomach ache.
- Feeling like your stomach is full (bloated belly).
- Borborygmi - the sound we hear from our stomachs as we digest food.
- Feeling tired all the time (fatigue).
- Nausea.
- Oily, discolored, and smellier stools than usual (steatorrhea).
- Unexplained weight loss.
What causes Tropical Sprue?
Experts still don't know exactly what causes it. But research suggests that it can occur when harmful bacteria enter the small intestine and damage cells called enterocytes . Enterocytes are the cells that line the inside of your intestines. These are the cells that help your body absorb vitamins and minerals.
Several types of bacteria are suspected to be responsible. For example, harmful strains of Escherichia coli (E. coli) , Klebsiella pneumoniae, and Enterobacter cloacae . These bacteria prevent the absorption of nutrients in the small intestine. Instead of those nutrients being absorbed into the bloodstream, they are passed out of the body in the stool.
Who is at higher risk of developing Tropical Sprue?
The most important risk factor is living in a tropical or subtropical (warm or semi-warm) region, or spending a month or more in such a region . The disease is rarely seen in countries such as Central America, Europe, Mexico, and the United States. Tropical sprue is probably not common in these countries because of the availability of clean water and good medical facilities.
What complications can occur if left untreated?
If tropical sprue is not treated properly, conditions such as:
- Macrocytic anemia: This occurs when the body does not get enough folate, vitamin B2, and vitamin B12. Simply put, it is a lack of blood.
- Malnutrition: This is a serious condition that can be life-threatening.
How does a doctor detect this?
When you see a doctor, he or she will first do a physical examination . He or she will ask about your symptoms and your general health. For example, whether you are losing weight without trying, or whether you get frequent infections. If you have traveled to an area where tropical sprue is common, your doctor may do some tests to find out the cause of your symptoms:
- Complete Blood Count (CBC): This checks for low red blood cell counts (anemia), vitamin B12, and folate levels.
- Comprehensive Metabolic Panel (CMP): This test can show abnormalities in essential electrolytes in the body.
- Stool tests: These tests are done to check for excess fat in your stool. Other stool tests may also be done to rule out other conditions with similar symptoms, such as giardiasis , strongyloidiasis , or cryptosporidiosis .
- Enteroscopy: This test can look inside your small intestine and take a tissue sample. A medical pathologist will examine the tissue sample to see if there are any changes in the small intestine that are related to tropical sprue.
What are the treatments for Tropical Sprue?
Doctors usually treat tropical sprue with a combination of antibiotics and nutritional supplements. You may be given:
- Tetracycline: This may need to be taken continuously for about six months.
- Folic acid supplements.
- Vitamin B12 injections.
How is Tropical Sprue treated in children?
Tropical sprue is very rare in children. If it does happen, the doctor will prescribe another antibiotic instead of tetracycline. Tetracycline can discolor children's teeth, which is a common side effect of this medication.
What happens if I have Tropical Sprue? Will it get better?
The good news is that tropical sprue can usually be completely cured with treatment . Your doctor will check you again (follow-up appointments) to make sure your red blood cell count and vitamin levels have returned to normal, and will also do blood tests.
However, people who live in areas where tropical sprue is common are at risk of developing the disease again.
Can Tropical Sprue be prevented?
If you are traveling to areas where tropical sprue is common, it is very important to avoid situations where you could be exposed to this disease or the bacteria that cause it. For example:
- If you eat fresh vegetables and fruits, only choose those that you can peel yourself.
- Make sure the food is cooked thoroughly.
- Only use canned or bottled beverages.
- Wash your hands often, especially before eating.
- Keep an alcohol-based hand sanitizer nearby.
No matter how careful you are, if you do get sick, seek treatment as soon as possible . Getting treatment early to kill the bacteria in your small intestine can reduce your risk of developing tropical sprue.
How do I take care of myself?
Tropical sprue can be a bit difficult for your digestive system . While you're recovering, focus on foods that are easy on your stomach. For example, bananas, rice, applesauce and toast (the BRAT diet) . Drink fluids that contain electrolytes to help prevent dehydration.
When should I see a doctor again?
If your tests confirm that you have tropical sprue, and your symptoms do not improve after treatment or get worse, you should definitely see your doctor again. Your doctor will then do more tests to see if your symptoms are caused by something other than tropical sprue.
What is the difference between Whipple's disease and Tropical Sprue?
Both of these diseases are caused by bacterial infections that affect the small intestine, preventing the body from absorbing nutrients. The difference is that Whipple's disease can also affect your nervous system, heart, and lungs.
Maybe you've dreamed of spending some time in a tropical country. No matter how careful you are, tropical sprue can be a real pain, and days of diarrhea and vomiting are no fun. But tropical sprue can also lead to serious problems like anemia and malnutrition.

If you think your symptoms are more than just a simple traveler's stomach ache, see a doctor without hesitation . Early treatment can cure tropical sprue and prevent complications. Remember, this is nothing to be afraid of, but it is definitely a condition that requires medical attention. Stay healthy!
