Fructose malabsorption

The first and most common cause of water melon in diarrhea is fructose malabsorption.

Fructose is known as a sugar that exists in numerous plants but in the highest concentrations in fruits. 

Fructose malabsorption occurs when your intestines are unable to break down fructose effectively during digestion. 

It is normally absorbed in the small intestine, but if it is not appropriately absorbed, it may travel to the large intestine and be fermented by bacteria, potentially causing cramps, bloating, and diarrhea.

This condition is a common symptom of larger conditions such as IBS, but it can also occur on its own.

According to Traditional Oven, there is approximately 6g of sugar in 100g of raw, natural watermelon, of which 3.36g is fructose.

Diarrhea after watermelon is a result of fructose malabsorption

Due to its fructose content, water is considered a high FODMAP food, which is a group of fermentable short-chain carbs that are either indigestible or slowly absorbed in the small intestine.


Can melon cause diarrhea? Yes, due to lycopene.

It is a carotenoid that provides fruits like watermelon their red color and according to the American Cancer Society, consuming more than 30 mg of lycopene per day.

However, it is also the reason watermelon give you diarrhea.

Watermelon contains approximately 9-13 mg of lycopene per 1.5 cups. 

As stated by a June 2014 study published in the EXCLI Journal, red-fleshed watermelon has 40% more lycopene than tomatoes.

Noting that other fruits like pink grapefruit and tomatoes also contain it, the amount watermelon gives can put you over the unofficial 30 mg threshold.

Diarrhea from watermelon is also due to high water content of this fruit, which is the answer to the question “can watermelon juice cause diarrhea?” as well.

Watermelons contain approximately 92% water, which is quite high and is most likely why they have the word 'water' in their name.

In fact, this is not likely to lead to watermelon juice diarrhea, but foods with high water content may potentially encourage bowel movements and may tip the scales too far in that direction.

Raise your blood sugar levels

Watermelon has a high glycemic index (GI) besides its high FODMAP content. 

As a result, eating too much watermelon may cause your blood sugar levels to rise, which is especially important if you have diabetes.

High GI foods (GI levels greater than 70) are likely to spike blood sugar levels, whereas low GI foods (GI levels less than 55) make a steady rise.

The GI of watermelons ranges from 72-80, which is high.

Whereas the GI may reveal how your blood sugar reacts to a specific carbohydrate-containing food, the glycemic load (GL) takes into account the serving size, making it a more precise measure of a food's impact on your blood sugar levels.

Despite being a low GL food (a GL of 5-6 per cup (152 grams), eating too much watermelon will raise its GL, most likely resulting in a blood sugar spike.

Thus, monitoring your blood sugar is critical if you have diabetes; and many people choose to wear the best smart watch with blood sugar monitor.

Cause skin’s orange discoloration

Though rare, one study discovered that eating too much watermelon can be associated with lycopenemia, a yellow-orange skin discoloration that is a variant of carotenemia.

    I've been having diarrhea for at least 3 months and the colors seem to alter between dark brown slightly red, red, and yellow which i have mostly. This may be caused by the watermelon I've been eating every day. But if anyone knows, please tell me.
