Doctors use a physical exam, medical history, and a variety of tests, including pulmonary function tests, to confirm an asthma diagnosis and rule out other conditions that may appear similar, such as seasonal allergies and chronic obstructive pulmonary disease (COPD). A patient's asthma severity will most likely be classified into one of four categories based on their symptoms
There are two types of asthma: "intrinsic" and "extrinsic".
Extrinsic asthma: is caused by allergens such as pollen, mites, dust, tobacco smoke, and so on, whereas intrinsic asthma is caused by a respiratory tract infection. Extrinsic asthma, which usually begins in childhood, is far more common than intrinsic asthma, which affects only a small percentage of the population after the age of 30.
Intrinsic asthma: on the other hand, is more difficult to treat due to obesity as one of the main risk factors and chronic symptoms.
After a series of tests and consideration of the patient's entire medical history, asthma allergy is diagnosed. A physical exam is performed after the inquiry, followed by lung function tests to confirm asthma.
Nocturnal asthma:
It is one of the asthma types in which people with asthma find it difficult to cope at night, and they experience symptoms such as wheezing and shortness of breath, which disrupt their sleep. These symptoms are common in people who have uncontrolled asthma. As per experts, the circadian rhythm is to blame. In addition, excessive humidity, a dirty pillowcase, a large meal before bed, undiagnosed sleep apnea, and other factors can trigger nocturnal asthma.
Asthma And Food Allergies:
Certain foods should be avoided by asthma patients because they may aggravate their symptoms. Food allergies and asthma can make life difficult for you. A food allergy is defined as an overreaction of the body's immune system to certain harmless proteins, resulting in the release of a chemical called histamine. Hives, rash, nausea, vomiting, and diarrhea are all signs that someone has developed a food allergy. Food allergies are commonly associated with foods such as eggs, milk, peanuts, tree nuts (cashews, almonds, filberts, etc.), soy, wheat, fish, shellfish, and shrimp. Food allergies and asthma attacks can be avoided by avoiding these foods.Asthmatic patients should avoid foods containing omega-6 fatty acids and trans-fats because they aggravate asthma symptoms. Processed foods, as well as some types of margarine, must be avoided.
