Knowing the symptoms of common allergies and their risk factors

An allergy is a hypersensitive reaction of the immune system to a foreign substance. The immune system is responsible for producing substances referred to as antibodies. When an individual suffers from allergies, their immune system generates antibodies that help in identifying the harmful allergens affecting the body.

The symptoms of allergies are dependent on the substance one has been affected with. The reactions can be mild, moderate or severe in nature.

Hay fever

Hay fever, which is also called allergic rhinitis, can result in sneezing, runny nose, itching in the eyes or the nose, and watery or swollen eyes.

Food allergy

An allergy, which has resulted from consuming a particular food item, can lead to a tingling sensation in the mouth, lips or face swelling up or anaphylaxis, which could pose a threat to one’s life.

Insect sting allergy

A sting from an insect can cause the affected portion to swell up considerably, cause an itching sensation across the body, and lead to shortness of breath.

Medication allergy

An allergy, caused by the consumption of some medication, results in an itchy skin, rash, hives, swelling on the face, wheezing, and anaphylaxis.

Atopic dermatitis

This is a skin condition, which also goes by the name of eczema. Apart from causing an itching sensation in the skin, it can also result in it peeling off.

Anaphylaxis

Anaphylaxis is a severe form of reaction that could pose a serious threat to the patient’s life if not controlled in the early stages. Some of the commonly observed symptoms of anaphylaxis are losing consciousness, low blood pressure, shortness of breath, light-headedness, skin rash, weak pulse, and nausea.

Causes of allergies

A person suffers from an allergy when their immune system considers a harmless material to be a threat. The immune system then proceeds to generate antibodies that keep a close watch on the substance that has been identified as an allergen. When the allergen comes in contact with the body again, the antibodies produce a variety of chemicals that cause symptoms of allergy.

Some of the common triggers of allergy are:

  • Airborne allergens like dust mites, pollen, mold, and animal dander
  • Food items like wheat, fish, eggs, peanuts, milk, shellfish, and tree nuts.
  • Insect stings, particularly from a wasp or a bee
  • Medicinal remedies that have penicillin content in them
  • Latex and a few other substances, which cause a reaction upon touching them

Risk factors of allergies

Family history
If members of your family have been prone to certain kinds of allergies, then there is a chance that you might suffer from them at some point of time. Families, which have had a history of suffering from a particular allergy, should get their younger members checked for any symptoms at an early age.

Children

Several studies have indicated that young children are at a higher risk of suffering from allergies than adults or older people.

Asthma or other allergies

If you are already suffering from an allergy, especially something like asthma, there is a chance that you will develop other kinds of allergies in due course of time.

5 most common food allergies

5 most common food allergies

Food allergy is common in both children and adults. It is a condition in which a person’s immune system erroneously identifies specific components in food, typically protein, as enemies. As a result, it triggers an immune response that causes inflammation and other symptoms, such as diarrhea, rashes, shortness of breath, and even life-threatening anaphylaxis. Though nearly any food can trigger an allergic reaction, the following are more likely to cause a problem. Peanuts Peanuts are one of the most common causes of food allergies in humans. And the biggest concern is that allergic reactions caused by them can be severe and potentially fatal. Researchers are not sure why some are allergic to peanuts, but they maintain that a family history of peanut allergy increases an individual’s risk. Milk Milk allergy is the most common food allergy in infants and young children. However, most children grow out of it as they age. The problematic components in milk are its proteins—whey and casein. Milk allergy must not be confused with lactose intolerance, which is the body’s inability to fully digest the natural sugar (lactose). Wheat Approximately two-thirds of children with wheat allergy grow out of it by adolescence. Nevertheless, many adults are allergic to any of the hundreds of proteins found in wheat, causing symptoms like nausea, abdominal pain, itching, and even anaphylaxis.
Odors as asthma triggers – What one needs to know

Odors as asthma triggers – What one needs to know

People who have eosinophilic asthma usually exhibit high levels of eosinophils, a type of white blood cell that helps build a strong immune system. However, when abnormally high levels of eosinophils come in contact with the cells present in the airways, they can cause inflammation. Eosinophilic asthma can also cause type-2 inflammation, resulting in decreased lung function. The following article specifically focuses on allergens like smells that trigger the symptoms of asthma. Symptoms of asthma A person who has inhaled asthma-triggering odors may exhibit symptoms like shortness of breath, wheezing when exhaling, and frequent coughing. Shortness of breath may be caused due to decreased lung function or inflamed air passages in the case of eosinophilic asthma type-2 inflammation. Odors that trigger the symptoms of asthma The symptoms may be caused due to a variety of allergens, including dust, dander, or pollen. While these allergens can be avoided to a certain extent, allergens like gases and aerosols can be a challenge to avoid. Statistics suggest that more than 40 percent of people with asthma report health problems due to odors. The odors that trigger asthma symptoms include: Household smells These include air fresheners, chlorine and bleach (present in cleaning products), colognes and perfumes, deodorants, furniture polish (wood varnish), nail polish remover, fireplaces, and wood-burning stoves.
6 worst foods for people with breathing problems

6 worst foods for people with breathing problems

Leading a regular life becomes quite challenging when one faces breathing troubles sporadically. Breath-related issues, such as shortness of breath, coughing, wheezing, and pain or pressure in the chest are usually symptoms of lung diseases like MAC disease and COPD. Certain foods we regularly eat can negatively affect our lungs and exacerbate breathing problems. So, this article lists some common foods one must avoid to ease breathing issues and control MAC disease and COPD symptoms. 1. Fried foods Fried foods, such as French fries, fried chicken, and potato chips, are among the unhealthiest foods anyone can eat. These foods can cause gas and bloating, making breathing more difficult in those suffering from breath-related conditions. Fried foods, being calorie-dense, can also lead to weight gain, which increases pressure on the lungs. 2. Salty foods Too much salt spells more trouble when you’re suffering from breathing problems. That’s because salt, or sodium, can cause fluid retention in the body, triggering high blood pressure and shortness of breath. Steer clear of various high-salt foods like canned soup, pasta sauce, and tortilla chips, and replace salt with spices and herbs in dinner recipes. 3. Processed meats Ham, hot dogs, sausages, and other processed meats are usually loaded with nitrates to improve color and prolong shelf life.

Foods and remedies to help manage Parkinson’s

Foods and remedies to help manage Parkinson’s

Parkinson’s is a degenerative neurological disorder that commonly affects senior individuals. However, there are times when patients are diagnosed with the early onset of the condition. The disease is associated with a lower amount of dopamine in the brain and damaged nerve cells. Dealing with a condition such as Parkinson’s does not have a specific to-do not-to-do plan; however, there are certain foods that are believed to aid in its management. Foods that help manage Parkinson’s Bananas Bananas contain magnesium, a critical nutrient that helps lower the risk of spasm and muscle cramps. Patients with Parkinson’s are also low on dopamine, an essential neurotransmitter that regulates communication linked to movement. Bananas contain tryptophan and tyrosine, both key building blocks of dopamine that help supplement this requirement. Berries Studies reveal that free radicals can damage healthy brain cells and worsen the cognitive symptoms linked to Parkinson’s. Blueberries, cranberries, strawberries, raspberries, blackberries, goji berries, and elderberries are loaded with essential antioxidants and vitamin C to combat this stress and boost cognitive function. Berries are also loaded with fiber that helps manage constipation, one of the critical discomforts linked to the disease. Broccoli Green vegetables are rich in fibers and antioxidants that actively help combat oxidative stress to minimize dopamine loss.

6 superfoods that help reduce cholesterol levels

Cholesterol is a naturally-produced essential fatty substance in the body. The type of fat found in the blood helps the body build healthy cells, thereby ensuring it functions smoothly. However, excess cholesterol is harmful as it can lead to fatty deposits in the blood vessels, narrow or clog the arteries and increase the risk of heart conditions. Below are six foods that help lower cholesterol levels and also improve heart health. 6 superfoods that help lower cholesterol levels Apples Apples are rich in a type of soluble fiber called pectin that brings down cholesterol levels by about 10 percent. It also helps reduce triglycerides, which is a type of fat in the blood. In addition to their fibrous content, apples also contain polyphenols, which could help control cholesterol levels. Avocados Avocado contains monounsaturated fatty acids or MUFAs, which keep the cholesterol levels in check and help in keeping the heart healthy. This fruit contains about 10 grams of fiber. You can pair it with whole grain, pumpernickel, or rye toast to make it even more fibrous. Add a squeeze of lemon juice or sprinkle some herbs like oregano for extra flavor. Dark chocolate Cocoa in dark chocolates contains flavonoids that control blood pressure levels and lower cholesterol.
