Can you eat too much watermelon?

Yes, too much watermelon can have serious side effects. Even if a watermelon is a very healthy fruit, you can have side effects from overeating the fruit. Some common side effects of eating too much watermelon include

  • Digestive issues 
  • Raise blood sugar levels
  • Discoloration of skin
  • Hyperkalemia

Digestive issues 

If you eat too much watermelon you can have digestive issues such as stomach pain, bloating, gas, diarrhea, and abdominal discomfort. This is caused because watermelon is high in FODMAPs, known as fermentable short-chain carbohydrates that are not easily digestible. 

If you have IBS you should avoid all food high in FODMAPs, including watermelon. 

Raise blood sugar levels

Watermelon has a high amount of carbohydrates, especially fructose, which can increase your blood glucose levels. If you eat watermelon without protein or fat, it is more probable that it can mess with your sugar levels. 

Also, it is known as a high glycemic food because, in a 2 hour period, watermelon can spike your sugar levels. If you have diabetes, try to eat small amounts of watermelon and always pair it with some protein such as yogurt, cheese, or nuts. 

Discoloration of skin

Too much watermelon can lead to orange discoloration of the skin because of lycopene. Lycopene is a powerful antioxidant that can also be found in tomatoes and carrots. 

Lycopene is also responsible for the red-orange color of the fruits. Too much lycopene can lead to carotenemia or orange discoloration of the skin. 


If you have renal disease or have any treatment where you are given IV potassium, more than one cup of watermelon can cause hyperkalemia. This is because watermelon is a fruit high in potassium. If you are a healthy person, you won’t get hyperkalemia or high potassium in the blood because of watermelon.
