In addition to its impact on blood sugar, excessive intake of guava leaf tea may also cause gastrointestinal discomfort. Reported side effects include abdominal cramps, diarrhea, acid reflux, and general digestive irritation. These reactions are more likely to occur when the tea is consumed in large quantities or on an empty stomach over a prolonged period.
Health professionals generally recommend moderation. Most guidelines suggest limiting consumption to one or two cups per day, depending on individual tolerance and health status. It is also advised that certain groups exercise caution, including pregnant or breastfeeding women, individuals with chronic kidney conditions, and patients with diabetes who are already under medical supervision.
While guava leaf tea may offer supportive benefits for cardiovascular health, inflammation reduction, and skin health, it should not be considered a replacement for medical treatment or a balanced diet. Its effects can vary significantly from person to person, and more clinical research is still needed to fully understand its long-term impact.
