allergies: pollen, dust mites, the warm weather arrives mascotasCuando allergic processes multiply. Allergies are extremely annoying stationary but these are simply inflammatory reactions of the upper airway hypersensitivity response.

This reaction occurs when there is contact with many substances that are present in the air we breathe. At the time of the spring bloom occurs in various plant species such as olives, bananas, grasses, etc. Cupressaceae. a high concentration of pollen.

Seasonal rhinitis occurs suddenly when the ambient level of pollen increases rapidly. This occurs in the months of May and July as the wind increases and expands the pollen as soon as it rains, the atmosphere is clean and decreases the amount of pollen in the air.

Seasonal allergy symptoms

Allergens cause an inflammatory reaction and cause dilation of blood vessels in the nasal membranes. This reaction leads to the following characteristic symptoms: continuous sneezing, nasal congestion, nasal and pharyngeal tingling, production of mucus, headache, earache and irritation of the eyes.

The processes are manifested as allergic conjunctivitis, asthma, urticaria, anaphylaxis, rhinitis or urticaria. Sometimes allergic processes occur seasonally and others have throughout the year due to frequent exposure to triggers.

The diagnosis of allergy requires a personal observation and immunological studies in which the patient underwent skin tests for exposure to the allergen extracts and substances that are supposed to be suspicious.

By obtaining a conclusive result, treatment is started immunotherapy with extracts extremely sensitizing increasingly administered under the skin or mouth, or making a drug treatment for the symptoms with steroids, bronchodilators, antihistamines and decongestants.

Apart from pollen, mold spores, mold, mites and dander remains of domestic animals also cause allergies.

Allergic conditions caused by the spores increase during wet weather, spider mites are a microscopic feed on human skin flakes and animal and can be found in blankets, mattresses or sofas.

The hair and dander of pets especially cats are potent allergens. Environment pollution, exposure to fumes from exhaust pipes, snuff and smoke also can lead to allergic reactions like.

To diagnose the lactose intolerance there is a type of test is called “breath hydrogen detection“. Usually this gas is not detected in the breath, but, when sugars such as lactose is not digested well, gut bacteria that “feed” these sugars can produce various gases, including hydrogen. This gas is absorbed into the bloodstream, transported to the lungs and exhaled.

But this test is expensive and in Argentina, is done only in some private institutions. This test is also used to determine the presence and quantity of some bacteria in the digestive system.

Another test for lactose intolerance is a blood test to measure the glucose level. First is extracted fasting, and another two hours after drinking a beverage containing lactose. The test is whether glucose undergoes a change. If the patient can not digest lactose, it is not divided into smaller portions, and the glucose level remains unchanged.

Regarding the existence of specific medications that can alleviate lactose intolerance, some publications mention certain drugs whose function is to make an enzyme replacement, ie provide the missing enzyme. However, they are not yet available in all countries.

Just try to medicate, and treat children with natural elements, ie, eliminating or reducing the amount of those foods that may cause intolerance.

In adults, the foods that cause food allergies are more common in crustaceans (such as shrimp, crayfish, lobster and crab), tree nuts such as walnuts, fish, eggs, peanuts (causing severe anaphylactic shock). In highly allergic people even minuscule amounts of food allergen (eg, 1 / 44 000 of a peanut) may cause an allergic reaction. The less sensitive but can tolerate a small amount of a food to which they are allergic.

In children, the pattern is somewhat different from that of adults. Foods that cause the most common food allergies are eggs, milk, peanuts, fruits (tomatoes and strawberries in particular). Children sometimes overcome their allergies, but adults do not usually get rid of them.

In addition, children more easily overcome allergies to cow’s milk or soy milk as allergies to peanuts, fish or shrimp. Adults and children tend to react to these foods when they eat more often. For example, rice allergy is more common in Japan and the cod allergy is most common in Scandinavian countries.

Allergies cross
An allergic reaction is defined by the manifestation of allergic reactions to foods like (eg chemically) to foods already known to cause an allergic reaction. If an individual has an allergic reaction that put his life in danger, the doctor advises her to avoid any similar food (which could cause the same reaction). For example, if a person has a severe allergy to shrimp, it will likely have an allergy (then called an allergic reaction) to crabs, lobsters and crayfish.

Food allergy induced by exercise (AAIE)
Exercise can induce an allergic reaction to food. This is the typical scenario. A person eats a particular food and then makes the exercise. During exercise, the body temperature rises, it begins to feel itching, feels dizzy, and is rapidly developing the characteristics of an allergic reaction (hives, asthma, abdominal pain, and even anaphylactic shock).

This illness is called food anaphylaxis induced by exercise, and occurs more frequently in adolescents and young adults. The remedy, which is a preventive measure really, is to not eat for 2 hours (minimum) before exercise.

How is food allergy treated it?
Avoid allergenic foods: the main treatment for food allergy is to exclude allergens from the diet. Once the food allergen is identified, it should not be consumed. For this, individuals must read lengthy and detailed lists of ingredients on the labels of every food they want to consume.

Many foods causing allergies (such as peanuts, eggs and milk) are found in dishes which are not normally associated. For example, peanuts are often used as protein supplements, eggs are found in some salad dressings, and milk in baking. Dietary guidelines require that ingredients be listed on labels.

People can avoid most of the foods they are sensitive if they read the labels carefully and, at the restaurant, if they avoid the dishes may contain ingredients harmful to their health.
