What are the Causes?

Why does avocado upset my stomach?

There are many reasons why someone might experience an avocado upset stomach. Still, the most common one is when their sensitive stomach can’t handle all the fiber.

However, there are several other probable causes. Let’s find out.

Fiber Intolerance

The average person meets their fiber needs through a diet that contains plenty of fruits, vegetables, whole grains, and beans. However, individuals with a low fiber intake tolerance may experience gastrointestinal (GI) obstruction, diarrhea, and gas or bloating.

Though a rich source of dietary fiber, they should be avoided if you have an upset stomach. They are not digested in the system and can lead to constipation or prolonged feelings of fullness.

Too much fiber in your stomach can cause diarrhea. Limiting eating to one serving at a time is best to avoid this.


Some people have allergic reactions to avocados. There are two main forms of allergy: tree-pollen allergy and latex-fruit syndrome.

Those allergic to tree pollen develop symptoms in the mouth and throat shortly after eating them.

Some people allergic to latex are also allergic to some or all fruits (particularly those in the citrus family). There is not much research that understands why. But it has been found that children with latex-fruit syndrome could risk having general hives, abdominal pain, and vomiting symptoms.

Fruit Sugar Malabsorption

Fruits are a healthy food choice for many, but not all. If you experience symptoms of fructose malabsorption, your intestinal system cannot metabolize fruit sugars efficiently. If you eat any sweet fruit, these sugars can lead to bloating or stomach pain.

Gastrointestinal problems for those on a FODMAP diet are most commonly attributed to fruit sugars or sugar alcohols which can’t be easily digested.

They contain sugar alcohols, which can create stomach problems for people with diabetes and fructose intolerance.

Sensitive To Chemicals

The other possible explanation could be a natural chemical found in the fruit.

It contains glutamates and amines like tyramine and histamine, whose levels increase with the ripening and softening of the fruit.

While many people can easily tolerate it, some sensitive individuals experience stomach upset when they eat them. This problem typically causes abdominal pain and other gastrointestinal issues such as gas, flatulence, or diarrhea.

Salicylates may also lead to heartburn, nausea, vomiting, stomach cramps, or diarrhea.

If you’re dealing with this issue, you can do a few things to help alleviate the problem.

Drink water

First, you must drink plenty of water when eating them to avoid upset stomach from dehydration.

Add more fat

Second, try using less fiber by adding more fat to your oils and grains. This will ease the digestion process for someone sensitive to fiber.

Eat smaller amount

Third, try eating a smaller amount at once instead of consuming the entire fruit in one sitting. This will help spread your digestion and make it easier on your stomach lining.

Add yogurt

The fourth thing you can do is add some yogurt to the dish if you’re using guacamole or mashed avocado.

Cut down on avocados.

Finally, if the tips above do not help this time, you might want to consider cutting down on avocados. This will allow your stomach lining some much-needed rest and healing time.

Those with sensitive stomachs must learn how to prevent from enjoying the many health benefits the fruit offers.
