Different types of drugs are the reasons for the disorder to happen. The medications with the highest level of risk include all those prescribed to control blood pressure (minimize it when it quickly goes up). It is better to avoid using an angiotensin-converting enzyme (ACE) in this case as it provokes Angioedema. Moreover, health care professionals recommend keeping away from the non-steroidal anti-inflammatory class of drugs like those, you take to reduce a headache.

There is nothing much to say about idiopathic form as it is not deeply studied. Health care providers cannot define the exact causes of this Angioedema. However, they can diagnose it. As for the hereditary form, it is only possible when patient’s parents or close relatives have the corresponding signs. The main symptom is low blood level of the C1 inhibitor (protein). Pregnancy and different injections may be the causes too.
