Carriers of thalassemia genes may have no symptoms (thalassemia minor), very mild symptoms with occasional crisis (thalassemia intermedia) or severe and life threatening symptoms (thalassemia major). [17] Alpha thalassemia major is generally fatal to the unborn child, as zero functional hemoglobin is produced during gestation.
Although complications during anesthesia are rare, potentially life-threatening consequences may occur if an anaphylactic reaction develops. The severity of the reaction whilst under anesthesia is because the anesthetist is only made aware of the allergy when it is severe enough to compromise the cardiovascular system and the respiratory system.
[6] [1] These symptoms typically start in minutes to hours and then increase very rapidly to life-threatening levels. [1] Urgent medical treatment is required to prevent serious harm and death, even if the patient has used an epipen or has taken other medications in response, and even if symptoms appear to be improving.

Heart attack, generalised anxiety disorders, panic disorder, depression, blood transfusion, bipolar disorder, anaphylaxis A sense of impending doom is a medical symptom that consists of an intense feeling that something life-threatening or tragic is about to occur, despite no apparent danger.
The cause for the disorder is related to a genetic mutation of the HBB gene. This gene is responsible for providing the instructions to produce beta-globin; one of the major components of hemoglobin. The two classification types of beta thalassemia are thalassemia major (also known as Cooley's anemia) and thalassemia intermedia. [30]
Plymouth native Maggie Habashy was diagnosed with exercise-induced anaphylaxis – a rare and dangerous allergy that can trigger anything from hives and vomiting to life-threatening throat ...
Untreated thalassemia major eventually leads to death, usually by heart failure; therefore, prenatal screening is very important. [9] Those with beta thalassemia intermedia (those who are compound heterozygotes for the beta thalassemia mutation) usually present later in life with mild to moderate symptoms of anemia. [8]
In its most severe form, a food allergy can lead to a life-threatening condition called anaphylaxis, which occurs when the airways swell. Symptoms of anaphylaxis constitute a medical emergency and ...
