Allergies – Stages and prevention

The immune system of our bodies is constantly fighting against viruses and bacteria to keep us healthy. However, in certain cases, the immune system may also end up fighting some substances that are not always harmful. When this happens, you experience an allergic reaction. The allergens are the substances that cause the reactions. With a little carefulness, you can prevent the allergies effectively.

The allergic development

Even though an allergic reaction can vary from person to person, it generally progresses in the same five stages:

  • Stage 1
    The allergen enters your body through food, air, or touch, and contact the cells in your body.
  • Stage 2
    Your immune system creates immunoglobulin E, which is a type of antibody.
  • Stage 3
    This antibody enters your gastrointestinal tract or respiratory tract but does not do anything.
  • Stage 4
    The next time when you are exposed to the same allergen, the immunoglobulin E treats it as a harmful substance and reacts with it.
  • Stage 5
    24 hours after the reaction, the immune system cells move towards the areas that were affected to release certain chemicals to treat it.

How to diagnose allergies

Your allergies can be diagnosed by a doctor. Before visiting him or her, you must recognize the symptoms of an allergic reaction. A mild allergy can lead to red and itchy spots on your skin, nasal congestion, rash, scratchy throat, and watery or itchy eyes. However, a more serious allergy can lead to abdominal pain, diarrhea, chest pain, nausea, dizziness, face swelling, palpitation, breathing difficulties, anxiety, weakness, or other symptoms. If you believe that you are having an allergic reaction then you must contact your doctor.

The doctor performs different tests to determine the kind of allergy you have and what has caused it. Elimination tests, blood tests, and skin tests are the most common form of tests that the doctor may order. The elimination test involves excluding different food items from your daily diet to determine which one causes your allergy. During a skin test, the suspected allergens are applied to your skin to observe how your body reacts. However, if the result from your skin test is inconclusive or it cannot be done for any reason, then the doctor orders a blood test. This test looks for antibodies in the blood to determine what kind of allergens you might have been exposed to. Once it is found, the doctor can help you treat or manage your allergy.

Prevention

Once you know what kind of allergies you have, you can start taking preventive steps to manage them. The most important thing is to avoid the allergens that result in your allergy. You must also regularly take the medicines that your doctor prescribes. If you experience severe allergic reactions, then your doctor will prescribe an epinephrine injection, which you must always carry with you. It is also important to wear a medical alert bracelet when you are going out so people around you are made aware of your condition.

Having allergies can be discomforting and scary. However, by taking the right preventive steps and medicines, you can lead a normal and healthy life.

Heartburn and GERD are often used interchangeably. However, heartburn is a common symptom experienced by people who suffer from acid reflux, and if heartburn occurs more than just twice in a week, the condition is known as gastroesophageal reflux disease (GERD). As per the National Institute of Diabetes and Digestive and Kidney Diseases, the condition affects as many as 20 percent of the country’s total population. Stages of GERD GERD is a progressive condition, and the treatment offered depends on the stage of the condition. How severely the reflux is taking place into the esophagus determines the stage of the condition. So, the various stages of GERD are: Stage I At this stage, the symptoms of the condition are mild and occur about once or twice the month. The treatment at this stage involves more lifestyle changes combined with some over-the-counter medications. Stage II When a patient is at this stage, the symptoms become more frequent and the need to take an acid-suppressive medication arises. If the medication is not taken, the symptoms of the condition can become severe and can interfere with the daily routine of the patient.

Male hair loss and its various aspects

Hair grows on all parts of the human body, apart from some places like the palm of the hands and the soles of our feet. Hair is essentially made of keratin, which is a type of protein. Keratin is produced on the outer layer of the skin in hair follicles. The follicles produce new hair cells and old cells are subsequently pushed out of the surface. There are 100,000 to 150,000 strands of hair on a human head, and one loses about 100 hair in a day. Thus, hair loss can be normal. However, we should only be concerned if there is hair loss at an alarming rate. Stages of hair loss Hair loss , also known as alopecia, is divided into different types: the age at which it starts, the duration of hair loss, and the area of the body.

Autoimmune diseases – All you need to know

The immune system of our body is constantly fighting against viruses and bacteria. Its job is to protect us from foreign cells that try to harm us. However, there are certain illnesses that can result in your immune system attacking your own healthy cells. These illnesses are known as autoimmune diseases. They cause the immune system to treat certain body parts as foreign elements and release auto-antibodies to attack the cells. Causes of autoimmune diseases Exactly what causes the autoimmune diseases is still unknown, but researchers around the world have come up with a few possibilities. While genetics can be at fault, your diet, certain infections, and exposure to specific chemicals may also result in autoimmune diseases. Types of autoimmune diseases There are many different types of autoimmune diseases that affect your immune system and cause it to attack the healthy cells in your body. Below is a list of the most common types. Type 1 diabetes This causes the immune system to attack the cells that produce insulin in the pancreas. Rheumatoid arthritis This illness forces the immune system to attack the joints in the body and results in stiffness, soreness, and redness. Multiple sclerosis The nerve cells in the human body are protected by a coating called the myelin sheath.
