Guava is generally safe and nutritious for most people. However, the fruit contains compounds that may not be good for everyone. You should avoid guava if you are allergic, pregnant, breastfeeding or have the following health conditions:

  • Gastrointestinal issues: You should avoid guava if you develop any unpleasant symptoms such as nausea or abdominal discomfort upon eating it. 
  • Eczema: People with eczema should avoid guava leaf extract because it may worsen the symptoms. Certain chemical substances in guava leaf extract can cause skin irritation, particularly in people with skin conditions such as eczema. Guava leaf extract when applied topically may cause skin irritation in some people.
  • Diabetes: People on diabetes medications must use guava leaf extracts with caution. Guava and guava leaf extracts help lower blood sugar levels. Thus, monitor your blood sugar levels while consuming such supplements.
  • Before surgery: Avoid using guava as a medicine or supplement at least two weeks before surgery because guava can lower blood sugar levels and increase the risk of bleeding.

Before using guava as a supplement for health benefits, talk to your doctor.
