Severe diarrhea can cause various concerns, such as malnourishment, dehydration and excessive weight loss. Diarrhea is a common condition that most people experience during their lifetime. It is a sign of another medical condition and needs to be assessed by a medical doctor. If you experience rapid weight loss from severe diarrhea, you need immediate medical attention because you are at risk of complications.
Causes
Severe diarrhea can develop from various reasons. Common causes of severe diarrhea include traveling, viral infections, food poisoning and certain prescription drugs, according to MedlinePlus. When you travel, you may be exposed to certain parasites or bacteria that your gut isn't accustomed to. Viral infections cause infection in the intestines that causes the digestive tract to empty itself to rid the body of the infection. Food poisoning occurs when you consume a food or beverage containing bacteria, viruses or parasites. Certain prescription drugs, such as antibiotics kill helpful bacteria in the gut that can lead to diarrhea.
Weight Loss Concerns
Weight loss from severe diarrhea is a concern because it is a sign that your body is not receiving the proper nutrition for growth and health. Excessive weight loss may also be a sign of malnourishment. Dehydration related to diarrhea can cause weight loss. When you develop severe diarrhea, it may be difficult to keep fluids in your system. This can cause dry skin, extreme thirst, fatigue and lightheadedness. Dehydration is a serious medical condition that can lead to death, if not properly treated.
Consideration
If you eat the wrong foods while you have diarrhea, you may make your condition worse. The National Digestive Diseases Information Clearinghouse states that certain foods need to be avoided when you have severe diarrhea, such as fatty foods, high-fiber foods, spicy foods and dairy products. You should eat small meals that consist of bland foods, such as crackers, boiled potatoes, bananas, rice and toast. Avoid beverages that contain caffeine or alcohol and do not drink apple or pear juice. Other fruits juices should not affect the condition.
Treatment
If you notice significant weight loss while experiencing diarrhea, you need to talk with your doctor. Although MayoClinic.com recommends avoiding the use of over-the-counter anti-diarrhea medications, they may be appropriate for your condition. If your doctor suspects that you're dehydrated, she may admit you to the hospital for hydration and to run tests to determine if any significant damage has been done.
