Can Green Tea Cause Constipation?

Green tea has many health benefits, from boosting immunity and providing a burst of energy to promoting weight loss. But, can it also cause constipation?

What is Green Tea?

Green tea is produced from the Camellia sinensis plant, a species of evergreen shrub native to Asia and the Himalayan region. To make green tea, the leaves are left to wither and dry. They are then sealed and rolled so that the leaves retain their color. The final product is then dried before being steeped in hot water.

Does Green Tea Cause Constipation?

Although green tea is known to have a number of health benefits, it can also have some adverse effects, one of which is constipation. Constipation can be caused by several factors, and green tea is one of them.

The caffeine in green tea has been linked to causing constipation. Caffeine is a stimulant, and it stimulates the large intestine, which may lead to dehydration and hard stools that are difficult to pass.

Green tea also contains tannins, which can make the stool hard and cause constipation. Tannins are present in many teas, including green tea, and act as antioxidants. They are also known to reduce the amount of water absorbed by the intestines, which can result in constipation.

Green tea also contains polyphenols, which can relax the gastrointestinal (GI) tract and slow down the transit time of stools. This can make it harder to pass stools and cause constipation.

Lastly, consuming large amounts of green tea can also be a factor in causing constipation. Too much green tea can interfere with the body’s absorption of fluids and nutrients, resulting in dehydration and difficulty in passing stools.

Preventing Constipation

If you are experiencing constipation after drinking green tea, there are a few steps you can take to prevent it:

  • Limit green tea intake: Consuming too much green tea can lead to constipation, so make sure to limit your daily intake to no more than 3 cups of green tea.
  • Hydrate: Make sure to drink plenty of water to avoid dehydration and keep your body hydrated.
  • Eat a balanced diet: Eating a balanced diet with foods high in fiber can help keep your digestion regular and prevent constipation.
  • Exercise: Regular exercise can help keep the muscles in your gastrointestinal tract toned and regular, preventing constipation.
  • Add herbal teas: Adding herbal teas, such as chamomile and ginger, to your green tea can help relax the GI tract and aid digestion.


Although green tea has many health benefits, it can also be a contributing factor to constipation. By following the above steps, you can help prevent constipation caused by green tea. Remember to always drink in moderation and consult your doctor if you experience any adverse effects.
