Diarrhea After Eating: Symptoms, Causes & More

diarrhoea after eating

Sudden and unexpected bowel movements can be embarrassing and a cause of serious health concern, especially if it has been occurring for a long time.

Diarrhoea after eating can not only hamper the nutrients in your body, but it can also be indicative of the prevailing of a more serious and long-term disease inside the body.

Naming the disorder and its components

This condition of diarrhoea after eating is medically called postprandial diarrhoea (PD). It’s not that easy to diagnose because sometimes it is connected with Irritable Bowel Syndrome, known as IBS-D. It is a symptom of other ailments in the body, such as E.coli infection or food poisoning.

So, what causes diarrhoea immediately after eating can be classified as acute or chronic.

What To Eat? After Phase Of Food Poisoning

Know your body through its symptoms

It’s important to clarify the intensity of your illness to begin diagnosis. Diarrhoea after eating can be acute or chronic. Diagnosing symptoms is the first step towards curing the disease.

The intensity of your diarrhoea may have one or several causes. It’s important to distinguish among them.

Why is acute diarrhea caused after meals?

Food poisoning and Bacterial infection

One of the most common reasons for acute diarrhoea is food poisoning. When edibles are not fresh or contaminated, bacteria grow on them, such as E. coli and Salmonella. These cause stomach cramps and abdominal pain that is followed or accompanied by diarrhoea immediately after eating.

Sugar malabsorption

All body systems may not easily digest naturally occurring sweeteners like lactose and fructose. Tolerance to these sugars varies by quantity. While some bodies can tolerate very high amounts before breaking down, many others are overwhelmed even by tiny quantities. So, when these sugars reach the intestine, it gets irritated and inflamed leading to diarrhoea after eating.

Lactose intolerance

Lactose is a type of sugar found in dairy-based products. People allergic to lactose may often have diarrhoea after ingesting any dairy item. Usually, the abdominal disturbance goes away once the stools have been discharged. But it might be a stronger infection if it happens regularly.

Medications

Certain prescribed or over the counter medicines may cause diarrhoea immediately after eating. Magnesium tablets and antibiotics are often causes of diarrhoea after eating.

So, how is chronic diarrhoea caused then?

Chronic diarrhoea is one where this symptom has persisted long and is, therefore, a health hazard. Read on to know more about some of the chronic causes of diarrhoea after eating.

Celiac disease

This is actually an autoimmune disease that causes a reaction to gluten-based products such as rye and barley. Constant ingestion of gluten-based products and ignoring the symptoms lead to chronic diarrhoea immediately after eating. Soon, the irritation of the intestinal cilia spreads to any food.

Colon cancer

Before you jump to conclusions, hold your breath. Not all diarrhoea after eating is a symptom of cancer. Blood along with your stools, fatigue and anaemia are some of the symptoms of colon cancer.

Irritable Bowel Syndrome

For patients suffering from IBS, either due to suppressed anxiety or the mere act of eating sets of diarrhoea.

Gallbladder operation

Patients who have had gallbladder removal surgery are more prone to digestive illnesses and should always check their diet. This surgery often creates bile acid diarrhoea (BAD), where there’s improper management of bile secretion, leading to a continuous digestion problem.

Microscopic colitis

This disorder can only be detected under a microscope and is preceded by symptoms of continuous, watery stools discharge. Diarrhoea immediately after eating is considered one of the symptoms of microscopic colitis.

Dumping syndrome

People who have undergone bariatric surgery will be familiar with this. Post this surgery, patients may have difficulty digestion as the food moves down quickly and may have to pass out stools immediately after eating. The condition is aggravated when gluten or lactose-based items are part of the diet without knowing the consequences.

How to deal with these kinds of diarrhea after eating?

While treatment depends on the diagnosis of your symptoms, there are certain things that you can do to handle diarrhoea immediately after eating.

Hydration

Increasing water and fluid intake is a must. Since watery stools dehydrate your body, it’s important to increase your ORS and vitamin water intake to fight against fatigue and weakness.

Meals and Nutrition

Having small meals without any spices eases the process of digestion, provides the required nutritional support and doesn’t disturb the intestines. It’s important to have these meals to survive through these bouts of diarrhoea.

Saying no to self-medication

Your days of playing doctor gets over the minute your real doctor takes over the diagnosis. Stop all over the counter medicines and focus on having prescribed medications and solutions as advised by the doctor.

Relaxing exercises and biofeedback

Since many important nutrients and water are discharged, and in extreme cases, blood, anxiety, fatigue, and anaemia sets in. To ride through this, it’s important to maintain body balance and mental health by performing curative, light exercises. Biofeedback mechanism involving sensors is also suggested to control bodily processes and maintain a healthy routine.

Banish trigger foods

Usually, there’s a sudden spike in cravings for everything that shouldn’t be eaten during abstinence and diets. Similarly, when you’re recovering from diarrhoea after eating, you may have cravings for spicy, oily and gluten-based foods. It’s wise to avoid it entirely. And if water gets boring, drink fruit juice.

Healthy living starts with healthy eating. Diarrhoea is something that is an effect of gastrointestinal disorders. These are fatal diseases with lifelong impacts. Controlling diets and going for necessary checkups are integral to maintaining proper gut health.
