Result of atherosclerotic plaque blocking one or more of the blood vessels that supply the heart. Can cause chest pain/angina pectoris occurring due to stress of exercise. If blockage completely impedes blood flow to the heart, a heart attack can occur.
It can be caused by insect stings, food, or medicines. It's caused by the release of histamine into your bloodstream and tissues. Histamine is an immune system chemical. Tongue or throat swelling can happen along with an allergic rash (hives), wheezing, diarrhea, and shock (low blood pressure).
A swollen tongue may be a symptom of a disease or medical condition, such as: Down syndrome; tongue cancer; Beckwith-Wiedemann syndrome; an overactive thyroid; leukemia; strep throat; anemia; When the tongue swells very suddenly, the likely reason is an allergic reaction. This can result in difficulty breathing. Difficulty breathing due to tongue swelling is a medical emergency. If this occurs, you should get medical help right away.
