Why Do Antibiotics Cause Diarrhea?

Diarrhea is a common side effect of antibiotic use, often resulting from the disruption in the balance of good and bad bacteria in the gastrointestinal tract. This can lead to digestive irritation, increased risk of illness due to harmful bacteria, such as Clostrioides difficile (C. diff), and severe diarrhea. Antibiotic-associated diarrhea is more common when multiple antibiotics are prescribed or an antibiotic is used for an extended period. Symptoms of antibiotic-associated diarrhea include a mild change in the population of intestinal bacteria, which may cause digestive irritation.

Some patients may find it easier to take certain antibiotics without diarrhea, but taking other drugs will cause diarrhea. Common culprits include clindamycin (Cleocin), ampicillin (sold under various brand names), and cephalosporins like cephalexin (Keflex). Symptoms of antibiotic-associated diarrhea include a mild change in the population of intestinal bacteria that may cause a bacterial infection with C. diff, leading to severe diarrhea.

The existence of bacteria in the digestive system with many different strains, including beneficial ones, can cause diarrhea when antibiotics kill good bacteria. When antibiotics kill good bacteria, they can promote the growth of bacteria that release toxins and cause diarrhea, such as Clostridium difficile.

Diarrhea is an unpleasant but common side effect of taking antibiotics, as they alter the number and types of bacteria present in the colon, leading to impaired absorption of carbohydrates. To treat or prevent this uncomfortable and sometimes serious problem, it is essential to understand the reasons behind antibiotic-associated diarrhea and how to prevent it.

How do you prevent diarrhea when taking antibiotics?

Eating yogurt or taking a so-called probiotic when you have to take antibiotics may help prevent the diarrhea that often accompanies antibiotic treatment.

That’s the conclusion of a study just published in the Journal of the American Medical Association. A team of California-based researchers combined the results of 63 randomized trials pitting probiotics versus placebo among almost 12, 000 men and women taking antibiotics. Those who took antibiotics plus probiotics were 42% less likely to develop diarrhea as those who got the placebo.

About one in three people who take antibiotics develop diarrhea. The symptoms usually start on the last day or two of antibiotic therapy, or a day or so after it has ended. The diarrhea is usually mild, with two to four loose stools per a lasting for a couple days. In most cases, it gets better quickly without treatment. That said, antibiotic-associated diarrhea makes some people very sick. The most severe form, called C. difficile colitis, can be life threatening.

Does diarrhea get rid of toxins?

Since diarrhea is your body’s way of getting rid of toxins, it is best to let it run its course.

How long does medication induced diarrhea last?

Diarrhea is a common adverse event resulting from over 700 drugs, with antimicrobials, laxatives, magnesium-containing antacids, lactose- or sorbitol-containing products, nonsteroidal anti-inflammatory drugs, prostaglandins, colchicine, antineoplastics, antiarrhythmic drugs, and cholinergic agents being the most frequently involved. New drugs like anthraquinone-related agents, alpha-glucosidase inhibitors, lipase inhibitors, and cholinesterase inhibitors are also likely to induce diarrhoea due to their pharmacodynamic properties. Antimicrobials are responsible for 25 of drug-induced diarrhoea, with the disease spectrum ranging from benign to pseudomembranous colitis. Several pathophysiological mechanisms are involved in drug-induced diarrhoea, including osmotic diarrhoea, secretory diarrhoea, shortened transit time, exudative diarrhoea, protein-losing enteropathy, and malabsorption or maldigestion of fat and carbohydrates. In clinical practice, there are two major types of diarrhoea: acute diarrhoea, which usually appears during the first few days of treatment, and chronic diarrhoea, lasting more than 3 or 4 weeks and appearing long after the start of drug therapy. Establishing a relationship between drug consumption and diarrhoea or colitis can be difficult when the time between the start of the drug and the onset of symptoms is long.

Should I eat yogurt while on antibiotics?

Yogurt is packed with bacteria, including Lactobacillus acidophilus, which can help reup your bacterial balance while you’re taking an antibiotic. You can also eat other foods containing prebiotics or probiotics, which are both connected with improved gut health. Fermented foods such as sauerkraut and kimchi contain probiotics.

If these foods aren’t appealing or you’re looking for a long-term solution, you might want to talk with your primary care provider or pharmacist about taking a probiotic supplement. These supplements contain the good bacteria to help keep your body balanced.

Beyond keeping your gut balanced and your digestive system functioning properly, keeping good bacteria in your body can also help you avoid other potential (and unpleasant) side effects from antibiotics, such as yeast infections. And you can still reap the benefits of the antibiotic going to work on the bad guys!

Is your colon clean after diarrhea?

Many people believe they have emptied out their colons after multiple episodes of diarrhea or that they can keep their colons empty by avoiding food. However, since stool is made up in large part of bacteria, fecal matter is continuously being formed.

• Bacteria
• Liquid
• Undigested food
• Dietary fiber
• Fat
• Minerals
• Protein

It’s the colon’s job to complete the process of digestion. Its main purpose is to absorb water and electrolytes from the material passed from the small intestine. This material is then formed into a stool that can be passed during the process of a bowel movement.

When a person experiences diarrhea, they are passing stool that has not been in the colon long enough to have had enough liquid absorbed to firm up the stool.

What to eat with antibiotic-induced diarrhea?

Bland foods – In general, foods for when you’re sick are also appropriate when you’re taking antibiotics. Plain or lightly salted crackers, peanut butter and non-citrus fruit are good choices. The BRAT diet (bananas, rice, applesauce, toast) can help with diarrhea from antibiotics.

Water – Staying hydrated is important, especially when you’re sick. It helps your body fight the infection, your medication to work properly and to combat some of the gastrointestinal side effects of antibiotics.

Fermented foods – Sauerkraut, kimchi, miso, fermented vegetables and kombucha contain beneficial probiotics that can support your gut and can help offset some of the unpleasant side effects of antibiotics. Yogurt and kefir can also be helpful, particularly the Nancy’s brand. Ensure dairy products are appropriately spaced from your antibiotic.

Probiotic supplements – Taking probiotics while you’re on antibiotics can help provide beneficial bacteria to your system and may also help with diarrhea. Some common brands include Culturelle, RenewLife and Florastor. If your provider prescribes probiotics with your antibiotic, they can be taken at the same time and don’t need to be spaced. Otherwise, follow the directions on the label. Your provider may recommend taking a probiotic supplement for up to a week after finishing your course of antibiotics.

How long does antibiotic diarrhea last?

About 1 in 5 people who take antibiotics develop antibiotic-associated diarrhea. Most often, antibiotic-associated diarrhea is mild and requires no treatment. The diarrhea typically clears up within a few days after you stop taking the antibiotic. More-serious antibiotic-associated diarrhea requires stopping or sometimes switching antibiotics.

For most people, antibiotic-associated diarrhea causes mild signs and symptoms, such as:

Antibiotic-associated diarrhea is likely to begin about a week after you start taking an antibiotic. Sometimes, however, diarrhea and other symptoms don’t appear until days or even weeks after you’ve finished antibiotic treatment.

Does medication still work if you have diarrhea after taking it?

Key takeaways: It’s possible that an oral medication may not be completely absorbed if you’re experiencing diarrhea. The longer you have diarrhea, the more likely a medication may not be completely absorbed.

Does diarrhea cleanse the stomach?

Diarrhea is a common symptom of various health conditions, including acute and chronic forms. It is often considered a self-limiting condition, as it is not always clear why it started or how it was resolved on its own. Factors contributing to diarrhea include food poisoning, infection, food allergies or intolerance, medication, stress, and other health problems.

Food poisoning is a common cause of diarrhea, particularly in developing countries where contaminated food or water sources can lead to bacteria, viruses, parasites, or other microbes. Infections, such as viral infections, are the most common cause of acute diarrhea, with strains like Salmonella, E. coli, and Shigella being involved. Food allergies or intolerance are genetically predisposed individuals who may have an abnormal immune response to certain foods or ingredients.

Medications, such as antibiotics, can unintentionally disturb the balance of beneficial bacteria in the digestive tract, sometimes killing helpful bacteria in addition to harmful ones. Stress can also cause diarrhea by affecting the gut-brain axis, which connects the central nervous system and the enteric nervous system. When neurotransmitters travel along this pathway to the gut, they can increase bowel movement in the large intestine, leading to diarrhea. Stress can also affect the muscles in the bowels and intestines, which can affect the ability of intestines to filter out harmful gut bacteria.

Other health conditions that may include diarrhea include irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), which usually manifest as Crohn’s disease or ulcerative colitis. Diarrhea can also be a symptom of colon cancer, though it is rare and typically presents in later stages when treatment options are limited.

Is yogurt good for diarrhea?

Yogurt can help prevent or treat diarrhea by containing probiotics, beneficial bacteria that can help prevent or treat various types of diarrhea. Infection-associated diarrhea can be reduced by up to 15 by consuming probiotics in the weeks before travel, while antibiotic-associated diarrhea can be reduced by up to 51 by taking probiotics and antibiotics. Probiotics found in yogurt can also reduce diarrhea caused by digestive disorders such as irritable bowel syndrome or ulcerative colitis.

All fermented dairy products, including yogurt, contain bacteria that convert sugars into lactic acid through fermentation. Some yogurt manufacturers have added digestive bacteria to their products, such as Bifidobacterium bifidum, Bifidobacterium lactis, Lactobacillus acidophilus, Lactobacillus reuteri, Lactobacillus rhamnosus, and Saccharomyces boulardii. These strains are effective in preventing and treating diarrhea in yogurt.

In conclusion, yogurt can be a beneficial food for children with diarrhea, as probiotics can help prevent and treat diarrhea caused by infections. Additionally, probiotics found in yogurt can reduce diarrhea caused by digestive disorders like irritable bowel syndrome or ulcerative colitis. It is essential to note that not all yogurts contain probiotics, as some bacteria are not considered probiotics due to their ability to provide health benefits.

What causes antibiotic-associated diarrhea?

Antibiotic-associated diarrhea refers to diarrhea that develops in a person who is taking or recently took antibiotics. One of the most serious causes of antibiotic-associated diarrhea is infection with a bacterium called Clostridioides difficile.
