The most prominent food that must be strictly avoided is fava beans and their products, in addition to exercising caution regarding certain medications and chemicals that may act as triggers. ## Fava Beans: The Primary Trigger Fava beans are a well-known trigger for red blood cell breakdown in individuals with G6PD deficiency, a condition also known as favism [\[4\]](). Hemolytic anemia can occur after eating fava beans or even inhaling pollen from fava bean plants. Therefore, it is strongly advised to completely avoid fava beans and their products, and to read ingredient labels carefully to ensure food products are free from them [\[3\]](). ## Medications and Chemicals Requiring Caution In addition to fava beans, there are many medications and chemicals that can trigger hemolytic anemia episodes in patients with G6PD deficiency. It is very important to always inform your doctor or pharmacist that you have G6PD deficiency before taking any new medication, including over-the-counter drugs and herbal supplements [\[3\]](). Review the exact medicine and dose with your clinician or pharmacist before use rather than relying on a general list banning an entire drug class. This includes antibiotics, antimalarials, painkillers, and combination products. Explain the enzyme deficiency and any previous hemolysis, and do not stop prescribed medicine yourself. Keep a medication list to support appropriate treatment choices and avoid confusion between brand names. [\[3\]]() Avoid exposure to naphthalene found in some mothballs and keep chemicals away from children. When seeking advice about a household product, provide its name and known ingredients rather than assuming that its smell or packaging establishes safety. [\[3\]]() Bacterial or viral infections can also lead to the breakdown of red blood cells in those with G6PD deficiency, requiring effective treatment of the infection under medical supervision [\[1\]](). ## Warning Signs and When to Seek Medical Help If you have G6PD deficiency and are exposed to any of the mentioned triggers, it is essential to monitor for the onset of symptoms of hemolytic anemia. These symptoms include pallor, jaundice (yellowing of the skin and eyes), dark urine, fatigue, shortness of breath, and a rapid heartbeat [\[1\]](). In the event these symptoms appear, you should contact your healthcare provider immediately. Severe cases may require a blood transfusion [\[3\]](). ## Living with the Condition and Prevention Living with G6PD deficiency requires constant vigilance and the avoidance of known triggers. A diagnosis does not necessarily mean constant symptoms, but rather the need for caution. Most people with G6PD deficiency can manage their condition and prevent symptoms by avoiding triggers [\[4\]](). It is recommended to consult with a healthcare provider to create a personalized plan to avoid triggers.
