Does green tea make you poop?

Drinking green tea can help you poop and offers additional digestive advantages for health. It can help reduce inflammation, support the intestinal microbiome and reduce the risk of colon cancer.

How green tea affect stool

Some people note that they poop more regularly after having drunk green tea every day. Scientists do not know exactly why, but there are a few theories, such as:

  • Caffeine contents: Like coffee, green tea contains caffeine. Caffeine has a laxative effect, which means that it stimulates your digestive tract and can make you want to have a sole.
  • Increased hydration: Another way that green tea can help you are increasing your consumption of liquid. Dehydration can cause constipation, so drink more liquid lubricates your digestive tract and results in easier and more frequent stools.
  • Reducing properties of stress: It has also been shown that green tea reduces stress levels due to the compounds it contains, such as L-Theanine. Stress is another trigger for constipation, so relaxing with a cup of green tea can give you the impression of having to go.

More digestive health services

1. Decrease in inflammation of the digestive tract

Green tea can help reduce inflammation in the stomach and intestines. Catechins, a compound found in green tea, are considered to be the source of its anti-inflammatory effects.

A study revealed that participants who drank 1 liter (L) of green tea in addition to the preparation of the standard intestine before a colonoscopy had much fewer nausea, vomiting and abdominal pain than those that did not drink green tea.

Subsequently, many more people in the green tea group completed their intestinal preparation and managed a successful colonoscopy. Researchers have theorized that this may be due to the anti-inflammatory effects of green tea on the digestive tract.

Scientists also believe that compounds found in green tea could help reduce inflammation for people with ulcerative colitis and Crohn’s disease, two types of inflammatory intestine disease. However, more research is required.

2. Reduction of starch digestion

Green tea blocks starch digestion, a complex carbohydrates that your body decomposes into sugar and uses as energy. Certain starchy foods (such as whole grains, legumes and vegetables) are healthy for you. However, others (such as white bread, cookies and fries) contain few nutrients and low fibers, which can increase your blood sugar.

Research shows that taking green tea extract (a concentrated green tea supplement) decreases digestion and absorption. However, a normal cup of green tea is less concentrated than green tea extract, so the effect on the digestion of starch can be less pronounced.

3. Modified intestinal microbiome

A large number of research shows that consumption of green tea can positively change the microbiome of your intestine. Your intestinal microbiome is the collection of microorganisms (such as bacteria) that live in your intestine. Everyone’s microbiome is unique and have different proportions of certain microorganisms has been linked to various health problems or health benefits.

Green tea can stimulate certain microorganisms to develop, while stopping the growth of less desirable species. The bacteria in your intestine can also feed on green tea compounds, releasing secondary compounds. Scientists believe that some of the advantages of green tea can be due to the way green tea modifies the microbiome and particles that these bacteria release.

4. Reduces the risk of colon cancer

Green tea can also reduce your risk of colorectal cancer, which starts in the large intestine.

Animal studies and small human studies have shown that green tea polyphenols (antioxidant compounds found in plants) have anti-cancer activity of colorectal. Researchers think that this advantage results from how green tea modifies the mouth and intestinal microbiome.

Are there disadvantages with green tea?

A disadvantage of green tea during digestion is that it can reduce the absorption of certain drugs in your intestines.

Studies have shown that consumption of green tea, whether on several occasions or just once, can make your intestines less likely to absorb corgard (Nadolol), a beta medication that reduces blood pressure and relieves thoracic pain.

Other drugs that can be less effective after drinking green tea include:

  • Crestor (Rosuvastatin), a stature used to treat high cholesterol
  • Program (tacrolimus), an immunosuppressant used after an organ transplant to prevent the body from rejecting the new organ
  • Jantoven (warfarin), a blood slimming used to reduce blood clots
  • Zocor (simvastatin), a stature used to reduce high cholesterol

Main to remember

  • Green tea can promote regular stools because of its caffeine content, its hydration services and its stressful properties.
  • The compounds of green tea, in particular catechins, can help reduce inflammation in the digestive tract.
  • It can positively modify the intestinal microbiome, block the digestion of starch and potentially reduce the risk of colon cancer.
