There are many different substances which can provoke an allergic reaction in certain people. The most common ones include substances found in nature, such as pollens from grasses, trees, weeds and some flowers, and many people are allergic to stings from insects like mosquitoes, bees, wasps, fleas and bedbugs. Some allergies can be caused by mould found in carpets, showers, laundry or even in the fridge, while others are provoked by dust in bedding, carpets and furniture.
The hair of animals, especially dogs, cats and guinea pigs, along with foods like red meat, chicken fish, eggs and wheat can also cause reactions. Some people can experience allergic reactions in response to medicines, including Aspirin, antibiotics, anticonvulsants and drugs used in chemotherapy, or to latex, found in baby bottles, gloves, bandages, handbags, or athletic shoes.
Allergies can produce different degrees of symptoms depending on the cause, and the severity of the reaction. Common symptoms include swollen eyes, a runny nose or sneezing, a rash or itching and diarrhoea or vomiting. If the symptoms are mild they may pass untreated or antihistamines or decongestants can be bought over-the counter at your local chemist. A doctor should always be consulted for more severe symptoms especially if the patient is having trouble breathing. The doctor will probably prescribe a steroid, a fast-acting bronchodilator to be inhaled, or other medicines to relieve respiratory problems.
Some allergies can improve with treatments like herbal teas, spicy foods, locally produced honey, eucalyptus oil or with prescribed medicines. Sometimes taking a shower can help. Allergies can be prevented or improved by making changes in your diet and by using natural, non-toxic soaps, and other beauty products which do not contain harsh ingredients. Washing your clothes thoroughly, cleaning your house well, and making sure that there are no sources of mould or pollen within your house can also help to prevent allergies.
