Side effects of garlic

The visuals below is the Side Effects Of Garlic and Reasons Why You Should Not Eat It Watch:

higher chance of bleeding

An increased risk of bleeding is one of the most dangerous adverse effects of eating too much garlic, especially if you’re on blood thinners or getting surgery.

This is due to the fact that garlic possesses antithrombotic qualities, which may help to prevent the formation of blood clots.

Despite the rarity of garlic-induced bleeding, one report described a case in which a person’s bleeding increased after consistently consuming 12 grams (or around 4 cloves) of garlic per day prior to surgery.

Another case study had a patient who had severe bruising and discoloration following surgery. The person may have been taking a nutritional supplement that includes fish oil and 10 mg of garlic concentrate, both of which have an impact on blood clot development.

licorice breath

Many different sulfur compounds found in garlic are thought to be responsible for its numerous health advantages.

However, when consumed in high quantities, these substances may result in unpleasant breath. As boiling reduces the quantity of these healthy sulfur compounds, this is particularly true for raw garlic.

Nevertheless, you can attempt a number of home cures to eliminate garlic breath.
digestive problems

Similar to onions, leeks, and asparagus, garlic has a lot of fructans, a type of carb that some people may find causes bloating, gas, and stomach pain.

In actuality, if a person has a fructan intolerance, they won’t be able to fully absorb a high fructan food in the small intestine. Instead, it remains undamaged while it passes through the gut and undergoes fermentation before entering the colon, which may cause digestive problems.

As a result, it’s common advice to limit garlic consumption for those on a low-FODMAP diet, an elimination diet meant to pinpoint particular foods that cause digestive problems.


You may want to think about reducing your intake of garlic if you have gastroesophageal reflux disease (GERD).

Heartburn and nausea are common symptoms of GERD, a disorder that develops when stomach acid leaks back into the esophagus.

Lower esophageal sphincter (LES) tone, or the capacity of the muscles at the bottom of your esophagus to seal and stop acid from entering, may be decreased by garlic. This could then result in acid reflux.

However, different meals have varying effects on patients with GERD. It’s probably not required to restrict your consumption if you discover that consuming a lot of garlic doesn’t result in symptoms.
