What are the side effects of eating too much watermelon?

The watermelon, which is high in potassium, magnesium, and vitamin C, benefits you with hydration and maintains the electrolyte levels, but you should still watch your serving size. Watermelon, like any other fruit, can be harmful to your health if consumed in excess. Watermelon has some negative effects, given its excellent nutritional profile.

Eating too much watermelon may lead to many unpleasant symptoms, some of which are described below:

May cause diarrhea and other digestive issues

Watermelon is a good source of dietary fiber as well as water. Excessive doses, on the other hand, may cause digestive issues such as diarrhea, bloating, flatulence, gas, and so on.

Watermelon contains sorbitol, a sugar molecule that has been linked to loose stools and gas problems. The presence of lycopene, a pigmented antioxidant that provides the watermelon with its vibrant color, is another key reason for such problems.

May cause glucose levels to rise

If you have diabetes, eating too much watermelon may cause your blood sugar levels to rise. Although it is a nutritious fruit, it does have a high glycemic index. Always get medical advice before adding watermelon to your daily diet.

May raise the risk of developing liver inflammation

People who routinely consume alcohol should refrain from eating excessive amounts of watermelon, because the high levels of lycopene in watermelon may interact with the alcohol, leading to liver inflammation. Severe oxidative stress on the liver can be detrimental to human health.

May cause overhydration or water intoxication

Water intoxication, also known as overhydration, is a condition in which your body holds too much water, causing you to lose salt. Watermelon consumption in high quantities may cause our bodies to retain more water.

If the surplus water is not excreted out, it can cause an increase in blood volume, resulting in swelling in the legs, tiredness, weaker kidneys, and other problems. It could also cause a loss of salt in the body.

May lead to cardiovascular problems

Potassium, an essential mineral that plays a variety of roles in maintaining good health, is found in abundance in watermelon. It helps in maintaining electrolyte function, keeping our hearts healthy, and strengthening our bones and muscles.

Too much potassium, on the other hand, might cause cardiac problems such as irregular heartbeat, a weak pulse rate, and so on.

May lead to orange discoloration of the skin

Though rare, one researcher found a relationship between ingesting too much watermelon and lycopenemia, a kind of carotenemia that results in a yellow-orange color of the skin.

Watermelons and other fruits and vegetables consist of lycopene, an antioxidant and a pigment that provides them with their unique red color.

If you ingest too much lycopene, it can accumulate in your skin’s outermost layer and alter the coloring of your skin. However, the research didn’t define how much watermelon was too much in this case.

Luckily, lycopenemia is a rare and totally reversible condition. Its adverse effects on the skin can be totally reversed by limiting the consumption of lycopene-rich foods like watermelon.

How much is too much watermelon?

Watermelon intake has no specified upper limit. If you’re not eating any other fruit, try to limit your watermelon consumption to 2 cups (300 g) every day.

The best thing you can do is to avoid these problems from occurring in the first place. Watermelon should be used in moderate amounts as part of a balanced diet. Also, keep an eye on the sugar content. If you eat too much, you will be at an increased risk of putting on weight.
