All about G6PD Deficiency


G6PD deficiency is an inherited condition in which the body doesn’t have enough of the enzyme glucose-6-phosphate dehydrogenase, or G6PD, which is essential for assuring a normal life span for red blood cells, and for oxidizing processes. This enzyme deficiency may provoke the sudden destruction of red blood cells and lead to hemolytic anemia with jaundice following the intake of fava beans, certain legumes and various drugs.
Most people with G6PD deficiency don’t have any symptoms, while others develop symptoms of anemia only after RBCs have been destroyed, a condition called hemolysis. In these cases, the symptoms disappear once the cause, or trigger, is removed. In rare cases, G6PD deficiency leads to chronic anemia
Symptom Triggers
Kids with G6PD deficiency typically do not show any symptoms of the disorder until their red blood cells are exposed to certain triggers, which can be:
illness, such as bacterial and viral infections (or fevers)
certain painkillers and fever-reducing drugs
certain antibiotics (especially those that have “sulf” in their names)
certain antimalarial drugs (especially those that have “quine” in their names)

Look out for less easily recognizable legumes such as alfalfa sprouts, peanuts, licorice or carob. Some legumes, such as fava beans cause severe hemolysis but several other legumes, beans and pulses cause less severe hemolysis but can still damage your health, Sulfites and foods containing them. Sulfites are used in a wide variety of foods, so check it out carefully.
  • Do not eat menthol, or menthol-containing foods such as breath mints or candy, tooth paste, mouth wash, but mint from natural mint oils is alright to consume.
