Cotton allergy refers to an allergic reaction that occurs when an individual is exposed to cotton. This can be cotton pollen, cottonseed oil, or even fabric. It is not as common as other types of allergies, but it can cause significant discomfort and complications in people who have it.
Cotton, used worldwide for manufacturing various goods, including textiles, may not appear as a typical allergen at first glance. However, an allergic reaction to cotton is a reality for some individuals. Exposure to cotton—be it in the form of cotton dust, cotton clothing, or cottonseed oil in food—can trigger an allergic reaction in sensitive people.
The immune system is designed to protect the body against harmful substances. When the body detects a substance it sees as harmful, it produces antibodies to neutralize it. This reaction is ordinarily protective; however, in the case of allergies, the immune system misidentifies a harmless substance like cotton as dangerous and overreacts, causing various physical symptoms.
Cotton allergy can manifest in several ways, from skin rashes when wearing cotton clothing to respiratory issues due to inhaling cotton dust, to gastrointestinal problems from ingesting cottonseed oil. Let's explore further.

What are the common symptoms of cotton allergy?
Symptoms of cotton allergy can vary based on how you're exposed. They may include skin reactions like redness, hives, itching, or eczema when you wear cotton clothing. Inhaling cotton dust can cause respiratory symptoms like sneezing, runny nose, and asthma. Eating foods containing cottonseed oil might lead to symptoms like itching mouth, swelling of lips or tongue, nausea, and diarrhea.
How is cotton allergy diagnosed?
A doctor can diagnose a cotton allergy through a skin prick test, where small amounts of potential allergens are pricked into the skin and any reaction is observed. Blood tests that measure the amount of specific antibodies to cotton can also help diagnose a cotton allergy.

Can I prevent cotton allergy?
Avoidance is the best prevention for cotton allergy. If you're allergic to cotton, avoid wearing cotton clothing, and check the labels of food products for cottonseed oil. Using a mask in environments where cotton dust is present can also help.
Is there a treatment for cotton allergy?
Yes, the treatment for cotton allergy typically involves managing the symptoms with antihistamines, corticosteroids, or other medications. Desensitization or immunotherapy, where small, gradually increasing amounts of the allergen are introduced to the body to decrease sensitivity, might also be an option in some cases.
What factors can affect the severity of cotton allergy?
Several factors can affect the severity of cotton allergy. These include the degree of sensitivity to cotton, the amount of exposure, and the mode of exposure (inhalation, skin contact, or ingestion). Other health conditions like asthma can also affect the severity of the reaction.
How often should I get tested for cotton allergy?
The frequency of testing depends on your symptoms. If you have ongoing or worsening symptoms despite treatment, your doctor might suggest periodic testing.
Who should I consult if I suspect I have a cotton allergy?
If you suspect you have a cotton allergy, it's best to consult with a doctor, preferably an allergist or immunologist, who specializes in allergies.
What are the potential complications of cotton allergy?
Complications can occur if cotton allergy leads to anaphylaxis, a severe allergic reaction that requires immediate medical attention. Cotton allergy may also lead to chronic conditions like allergic dermatitis or asthma.
What are the normal values for a cotton allergy test?
Cotton allergy tests, whether skin prick tests or blood tests, don't have "normal" values. A positive or negative result indicates the presence or absence of an allergic response to cotton.
Can cotton allergy be outgrown?
While food allergies are often outgrown, non-food allergies like cotton allergy are generally not. However, sensitivity can decrease over time, especially with proper management.
Is cotton allergy genetic?
Allergies, in general, have a genetic component, meaning they often run in families. If your parents or siblings have allergies, you may be at a higher risk of developing an allergy, including cotton allergy.
Is cottonseed oil safe for someone with cotton allergy?
Cottonseed oil is typically highly refined, and most allergenic proteins are removed during the refining process. However, reactions have been reported, so it's best to consult your doctor.
Are there alternatives to cotton for someone with cotton allergy?
Yes, alternatives to cotton for clothing and bedding include synthetic materials or natural fibers like silk or bamboo. Check with your doctor or allergist to determine what's best for you.
Can cotton allergy cause seasonal symptoms?
If you're allergic to cottonwood pollen, you may experience seasonal symptoms during the time when these trees are in bloom.
How do I know if my symptoms are due to cotton allergy or something else?
An allergy test is the most reliable way to determine the cause of your symptoms. If cotton is a suspected allergen, avoiding it and observing any changes in your symptoms can also provide clues.
Although cotton allergy is not the most common type, it can cause considerable discomfort to those affected. Understanding the allergy, its causes, symptoms, and how it is diagnosed and managed, is key to dealing with it effectively. If you suspect you or a loved one may be dealing with a cotton allergy, do not hesitate to reach out to a doctor for help.
