Diarrhea and Abdominal Discomfort: An Unwanted Side Effect of Colds

Understanding Cold and Diarrhea

It's common to experience gastrointestinal symptoms when you have a cold. The same viruses that cause upper respiratory symptoms can also infect the intestines, leading to abdominal pain, nausea, vomiting and diarrhea. Additionally, some cold medications and treatments can irritate the digestive system.

Diarrhea is characterized by loose, watery stools that occur more than three times per day. Viruses are a common cause of infectious diarrhea. The stomach flu virus rotavirus accounts for many cases, but cold viruses like rhinovirus and coronavirus can also spread to the digestive system.

How Colds Can Lead to Diarrhea

There are a few reasons why colds often coincide with diarrhea:

• The cold virus infects your gut
• Medications cause side effects
• Your immune response triggers gut inflammation

When you inhale cold viruses, they can take hold and replicate throughout your respiratory tract. But some types also continue traveling downwards to invade intestinal cells. This viral gastroenteritis leads to diarrhea as excess fluid gets dumped into the bowels.

Medication Side Effects

Certain over-the-counter cold remedies and antibiotics designed to treat secondary infections contain ingredients that can irritate your digestive system:

• NSAIDs like ibuprofen or naproxen sodium
• Decongestants including pseudoephedrine or phenylephrine
• Some herbal supplements
• Antibiotics

Always read medication labels thoroughly and follow dosing directions to avoid gut-related reactions.

Immune Response

Your body mounts a nonspecific immune reaction to viral colds involving inflammation. This defensive response can sometimes overreach and affect healthy gut bacteria or other parts of the digestive tract.

Furthermore, your intestinal microbiome gets disturbed whenever you have any illness. Beneficial bacteria die off, allowing populations of bad bacteria to expand. These shifts correlate with diarrhea and other digestive issues.

Treating Cold and Diarrhea Symptoms

Most cases of cold-related diarrhea resolve on their own without complications. But anti-diarrheal home remedies can help mitigate symptoms.

OTC Medications

Over-the-counter medications that absorb fluid in the intestines can provide relief for diarrhea. Look for these active ingredients at your local pharmacy:

• Bismuth subsalicylate (Kaopectate, Pepto-Bismol)
• Attapulgite (Kaopectate)
• Loperamide (Imodium)

Use these medications cautiously and only how they are intended. While they alleviate diarrhea, they will not treat an underlying intestinal infection.

Probiotics

Probiotic supplements contain beneficial live bacteria similar to those normally present in a healthy gut. They help restore microbial balance, improve immune function, and normalize digestion.

Yogurt with active cultures can also introduce good bacteria. Look for labels listing specific strains like Lactobacillus or Bifidobacterium.

Chicken Soup and Broths

Warm liquids are very soothing to an upset stomach. Bone broth and chicken soup provide hydration and nutrients while being easy on your digestion.

Avoid extremely spicy, fatty, or coffee and alcohol while symptoms persist. Dont force solid foods until the diarrhea lets up.

Oral Rehydration Solutions

Dehydration occurs rapidly when you have frequent, watery bowel movements. Besides water itself, oral rehydration beverages contain the proper balance of salts and sugar to replenish essential fluids and minerals.

Pedialyte and sports beverages like Gatorade can work, but the ideal ratio is:

• Water
• Sodium chloride
• Sodium citrate
• Potassium chloride
• Glucose

Making your own rehydration drink is straightforward and very cost-effective. Talk to your doctor if any signs of dehydration arise, like excessive fatigue, dry mouth, decreased urine output or very dark urine.

When to Seek Medical Care

Contact your healthcare provider if cold-related diarrhea is severe or accompanied by:

• Blood or mucus in stool
• High fever above 101F (38C)
• Signs of dehydration
• Extreme pain or bloating
• Persistence beyond two days

Immediate medical attention is vital whenever infants or toddlers get intestinal distress.

Also get evaluated if you recently took antibiotics or traveled abroad before the onset of symptoms.

Diagnostic Testing

To identify any underlying infection, the doctor can order a stool analysis. They will also consider blood work to assess dehydration.

If no obvious cause presents, you may need imaging, like an abdominal X-ray, CT scan or colonoscopy.

Treatment Options

For diagnosed infections, appropriate antibiotics or antiviral medications are warranted. IV fluid therapy rapidly corrects dehydration. And biologic drugs can relieve inflammatory bowel diseases.

A few days of clear liquid diet helps rest the digestive tract until acute gastrointestinal illness resolves. Probiotic supplements restore equilibrium to your gut microbiome afterward.

Preventing Cold and Diarrhea

The most effective way to avoid intestinal issues whenever you have a cold is through good hygiene and healthy habits:

• Wash hands frequently
• Disinfect shared surfaces
• Avoid sick contacts
• Drink lots of fluids
• Eat yogurt and fiber
• Take probiotics
• Get adequate rest

Practice these precautions vigilant whenever cold and flu season hits. Stay up-to-date on vaccinations as well.

See your doctor at the first signs of cold symptoms for early detection and treatment if you are in a high-risk group for complications. This includes infants, elderly, pregnant women, and immunocompromised individuals.
