Pregnancy changes your body in strange ways, and if you have allergies, you may notice that your reactions are different for a while.
Allergies can be a nuisance, especially when you’re pregnant and your body is erratic. They can, however, be safely treated, so you don’t have to suffer from your allergies during pregnancy.

Allergies During Pregnancy
Allergies are caused by the body’s immune system overreacting to a protein. These proteins could be derived from foods, pollens, house dust, animal hair, or moulds. They are known as allergens. The term allergy refers to the immune system’s reaction to a non-toxic substance as if it were toxic.
Allergies during pregnancy are especially common in pregnant women, even in those who have never had long-term allergies before. In other words, new allergies can develop during pregnancy. In other cases, allergies that were previously present may worsen.
Is it possible to develop allergies while pregnant?

Yes, allergies can occur during pregnancy, sometimes for the first time and certainly if you have a history of them. Allergies are common during pregnancy, but not all women who have them are long-term allergy sufferers. Many women who have no prior allergies only experience symptoms during pregnancy.
Types of Allergies
Every individual is unique, and allergies are no exception. While some reactions are more common than others, your allergies (and how your immune response manifests) will be unique to you. The following are the most common types of allergies:
-
Pollen Allergies
Also known as Hay Fever, allergies to pollen in the air can cause symptoms similar to the common cold, such as sneezing and coughing.
-
Food Allergies
Food allergies can be mild to severe. Furthermore, not all foods must be consumed in order to cause a reaction. Topical application of the food can also cause reactions in some cases.
-
Drug Allergies
Allergic reactions to drugs and pharmaceuticals can have a wide range of consequences with varying degrees of severity.
-
Pet Allergies
One of the leading causes of allergies is pet dander. These allergies can sometimes become more severe when you’re pregnant.
-
Allergies to insects
Insect bites and bee stings can cause severe allergic reactions in some people.
-
Mould Allergies
While mould spores in the air are not uncommon, certain types can cause mild to severe allergic reactions.
-
Latex Allergies
Some people are allergic to latex, causing skin irritation or other reactions.
Food Allergy During Pregnancy
Food allergy and food intolerance are frequently confused because symptoms of food intolerance can mimic those of food allergy. Food intolerance, on the other hand, does not involve the immune system and does not result in severe allergic reactions (known as anaphylaxis). Food intolerance is also not detected by allergy testing.
Food intolerance can be a difficult concept to grasp, and doctors are no exception. Foods can sometimes increase the frequency and severity of migraine headaches, rashes (such as hives), or stomach upset from irritable bowel syndrome.

Food intolerances and allergic reactions can change during pregnancy; for some pregnant women, existing intolerance improves, while for others, it worsens. Increased hormone levels in the body are most likely contributing to these changes. Also, keep in mind that most food intolerances will not harm you or your baby.
If you’ve ever had food allergies, talk to your practitioner and an allergist about whether you should consider restricting your diet in any way while pregnant and/or breastfeeding. The recommendations may differ slightly for you and your baby.
Food Intolerance Symptoms
Food intolerance symptoms can include:
- nervousness
- tremor
- sweating
- palpitations
- rapid respiration
- migraine, headache
- diarrhoea
- sensations of burning on the skin
- tightness in the neck and chest
- breathing difficulties – asthma-like symptoms
- allergy-like symptoms

- clogged nose
- rash on the skin (eczema)
- Urticaria (skin becomes red and raised)
- diarrhoea, stomach cramps
- breathing problems, such as wheezing and asthma

What Are the Dangers of Allergies in Pregnancy?
When you’re pregnant, allergies pose very little risk to you or your baby. Severe allergic reactions, such as anaphylaxis, will generally pose the most significant and severe risk to expectant mothers. Anaphylaxis can be treated with an injection of epinephrine (an epi-pen), so carrying one with you is usually recommended if you have a history of severe allergic reactions.

The other two risks posed by allergies are secondary in nature. Allergies can disrupt your sleep, nutrition, and overall health. Such interruptions may pose some health risks if they continue for a long enough period of time. Similarly, some allergy medications can be hazardous to your infant.
How To Prevent Allergies During Pregnancy?
There are things you can do to manage and prevent food allergies while pregnant.
1. Bring your own food
You may want to bring your own food into the hospital for the birth, at least until the hospital kitchens can accommodate your needs.
2. Adrenaline devices
If you have an emergency adrenaline device, such as an EpiPen or Anapen, consult with your allergist about the best way to use it during pregnancy.
3. Managing reaction to food
If you have a food allergy or are restricting your diet due to food intolerance, you may need to be creative when it comes to eating a healthy pregnancy diet. You can ask to be referred to a dietician if you need assistance creating a great new, baby-friendly diet.
If you suspect you have a food allergy or intolerance, consult your doctor before changing your diet. If you have a medically diagnosed food allergy and are concerned about not getting enough nutrients during pregnancy, consult your midwife or doctor.
Depending on your allergies, you may be referred to a dietician to assist you in selecting alternative foods that will provide you and your baby with the nutrients you require.

4. Eat healthy
The most important thing expectant mothers can do, according to doctors, is eating a healthy diet rich in fruits and vegetables, fish, and vitamin D. Consuming these foods may lower a child’s risk of developing allergic diseases. Before making any dietary changes during pregnancy, consult with your doctor.

Is It Safe to Take Allergy Medications While Pregnant?
- Antihistamines
Antihistamines may or may not be safe to use during pregnancy, so consult your doctor first. The most prescribed medication is Benadryl (diphenhydramine). Loratadine is usually considered safe, but check with your doctor first; some won’t give the go-ahead, especially during the first trimester.
Some doctors will prescribe Chlorpheniramine and triprolidine on a limited basis, but most will advise you to find an alternative.
- Regular decongestants
Regular decongestants containing pseudoephedrine or phenylephrine (such as Sudafed, Claritin-D, and DayQuil) are not recommended for pregnant women, particularly during the first trimester. Following that, some doctors allow limited use (once or twice for a day or so), because using decongestants more frequently can restrict blood flow to the placenta.
Don’t worry if you’ve already taken them; simply notify your doctor before taking them again. Vicks VapoRub is completely safe when used as directed.
- Nasal sprays
Nasal sprays containing steroids are generally considered safe for pregnant women, but consult your practitioner for brand and dosing recommendations. Nasal strips and saline sprays are always appropriate. Avoid nonsteroidal nasal sprays containing ozymetazoline (such as Afrin) unless your doctor has given you the all-clear.
