Diagnosing Asthma
It can be difficult to diagnose asthma, because its symptoms often resemble those of other respiratory or heart disease. The diagnosis is usually based on a description of symptoms, the set of medical history, physical examination and the results of some laboratory tests. Among diagnostic tests, include pulmonary function, blood tests, chest x-rays and allergy tests.
The pulmonary function represents a series of tests to measure lung function. The most common is the spirometry test, which uses a device called a spirometer to measure the quantity and flow (flow) of air entering the respiratory tract, then emerging. Evaluation of peak expiratory flow is another test to measure lung function. Using a peak flow meter, measure the rate at which air is expelled from the lungs. You can use this device to monitor asthma at home. Read the rest of this entry »
Food Allergy
A food allergy occurs because of a hypersensitivity caused by taking or eating a certain food.
In young children, the most common allergies are caused by the following foods: eggs, milk, shellfish, nuts, citrus and tomatoes. Adults is less common in this type of allergy.
The person before making an allergic reaction to food, must have been previously exposed to such food at least once. Allergic symptoms appear the second time the person eats the food. This time, reacting antibodies that have occurred with the ingested food, histamines are released which give the reactions.
Symptoms may include:
- Itching in the mouth.
- Difficulty breathing.
- -Stomach pain.
- Vomiting.
- Diarrhea.
- Rash.
- Asthmatic bronchitis or asthma.
- Allergic rhinitis.
There is no medicine to prevent the onset of symptoms. But the picture can be prevented if detected what foods that cause the reaction and not consumed.
Similarly it is advisable to ask the doctor a drug, for use in an emergency and to counteract severe reactions that can cause a complication.
