The Effects of Anaphylaxis on the Body

You may have a food intolerance or a minor allergic reaction to something you come into contact with, but that pales in comparison to anaphylaxis. Almost any substance can be an allergen, including foods and insect bites or stings. The cause can’t always be pinpointed. The first time you’re exposed to the substance, your immune system learns to recognize the foreign invader. In anaphylaxis, when you’re exposed again, your immune system has an exaggerated response that affects the whole body and may put your life in danger. Symptoms may begin within seconds and they can progress swiftly.

The first line of treatment is usually adrenaline, because it can turn things around quickly. Once you’ve experienced anaphylaxis, you’re always at risk, so you should take great caution to avoid the triggering substance. Your doctor will probably prescribe adrenaline in the form of a prefilled autoinjector that you can carry with you. If you need to use the autoinjector pen, you can inject yourself or have someone else do it for you. You should always seek medical help after using adrenaline. Symptoms sometimes return, but usually within a 72-hour period.

Immune System

Your immune system fights antigens like bacteria, viruses, and fungi. It learns to recognize these harmful substances and works to neutralize them. Once your immune system has come into contact with an antigen, it stores the information for future use. When it’s doing its job, you don’t get sick.

Sometimes, when you come into contact with that antigen again, your immune system overreacts, blowing the event out of proportion. Far too much histamine and other inflammatory chemicals are quickly released into your system. This causes a wide variety of problems that can have devastating results.

Adrenaline is a hormone produced naturally by your body. In anaphylaxis, an extra dose can help increase blood flow throughout your body and help reverse the immune system’s aggressive response.

Respiratory System

Inflammation in the respiratory system can cause the bronchial tissues to swell. Symptoms include shortness of breath and difficulty breathing. It can also cause fluid in the lungs (pulmonary edema) and cough. You may make high-pitched or wheezing sounds when you breathe. A feeling of tightening in the chest and chest pain are common. Respiratory distress is a life-threatening emergency requiring immediate medical attention. Untreated, it can lead to respiratory arrest. Patients with asthma are at particular risk.

Skin (Integumentary System)

One of the more obvious signs of anaphylaxis can be seen on the skin. It may start out as itchiness and redness, or just a mild warming of the skin. It can progress to welts, or hives that hurt when you touch them. If your respiratory system is in trouble, skin may turn blue from lack of oxygen. Pale skin means you’re going into shock.

Circulatory System

In anaphylaxis, small blood vessels (capillaries) begin to leak blood into your tissues. This can cause a sudden and dramatic drop in blood pressure. Other symptoms include rapid or weak pulse and heart palpitations. When major organs don’t get the blood and oxygen they need to perform, your body goes into anaphylactic shock. This is a life-threatening medical emergency. Untreated, you are at great risk of damage to internal organs or cardiac arrest.

Digestive System

Even if your reaction is usually mild, food allergies put you at increased risk of developing anaphylaxis. Digestive system symptoms include bloating, cramps, and abdominal pain. You may also have nausea, vomiting, or diarrhea.

Central Nervous System

Even before the first physical symptoms occur, some people have a weird feeling – a sense that something bad is about to happen. Others describe a metallic taste in their mouth. Inflammation in the central nervous system can make you lightheaded or dizzy. Some people get a headache. There may be swelling of the eyes. The lips and tongue can swell enough to make it hard to talk. If the throat swells, it can block your airway. Anaphylaxis can cause mental confusion, anxiety, and weakness. Other symptoms include slurred speech, hoarse voice, and difficulty talking. As your body goes into shock, loss of consciousness occurs.
