A food allergy occurs when someone’s immune system reacts adversely to a particular type of food. When this happens it causes inflammation in certain bodily tissues and can even be life threatening. A food allergy should not be confused with food intolerance because, although in both situations the body can react to even a very small amount of food, food intolerance is not caused by an individual’s immune system; rather, it’s the digestive system.

Although actual food allergies are very rare and tend to run in the family, some people avoid consuming specific foods because they are under the mistaken assumption that they’re allergic to them. On average, only one in hundred adults and three in a hundred infants have food allergies. An individual would be more at risk if they or their family suffer from any allergic conditions such as asthma, eczema or hay fever. Only a medical professional will be able to diagnose somebody as having a food allergy.

Food Allergies

In principle, people could be allergic to any type of food, but the most common ones appear to be the following: milk, fish, shellfish, eggs, wheat, soya beans, peanuts and certain fruit and veg.

Food allergies are usually diagnosed by blood or skin tests, or a going through a food elimination program.

When the heart is unable to pump blood around the body efficiently, it is known as heart failure. Heart failure can affect either the left or right side of the heart, or in some cases, both sides. The condition can be brought on by a number of diseases including high blood pressure, heart valve disease, blood clot in the coronary arteries and heart muscle disease.

Symptoms include shortness of breath, breathing problems, coughing, fatigue, leg swelling, eczema type rash and accumulation of fluid in the organs or abdominal cavity. Heart failure is usually diagnosed by a combination of medical history along with an examination that will check out such issues as heart sounds, heart rate, heart murmurs, fluid on the lungs, swollen legs, swollen neck veins or an enlarged liver. It can also be diagnosed by means of a chest x-ray, an ECG and blood samples. Doctors can also find out what caused the heart failure by performing additional blood tests so certain viral infections can be spotted, an ultrasound of the heart, a coronary artery examinations (done by injecting a dye into the left and right coronary arteries), exercise testing carried out on a treadmill and by taking a biopsy of a small bit of heart muscle.

Heart Failure

Ways to avoid heart failure include stopping smoking, a change of diet as well as avoiding overeating, exercising more often and getting problems such as high blood pressure or high cholesterol treated in a timely manner.

Drug allergies are adverse reactions to medication drugs and these reactions can be separated into three groups. First are those not actually related to the drug in question at all, but are coincidental and attributed to other mitigating factors associated with the illness or disease. Second are common predictable reactions like side effects related to taking other medication at the same time, or having an overdose. The third is unpredictable and uncommon reactions of which quite a few are allergic reactions that typically involve the immune system, being either immediate or delayed in reaction.

Allergic reactions can vary greatly from simple, slight rashes to very severe anaphylactic reactions of the immune system. Some drugs that can cause allergic reactions include heart drugs such as ACE inhibitors, antibiotics like penicillin, anesthetic drugs such as muscle relaxants, morphine, aspirin like drugs such as ibuprofen, chemotherapy drugs, antiseptics like iodine, vaccines such as tetanus, and colorings or preservatives in certain medications.

Reactions usually occur within one hour of taking the medication and can involve a measle-like rash that is very itchy. Some life threatening reactions may involve skin blistering with peeling accompanied by fever.

Common Allergic Reactions

Treatments of various drug allergic reactions involve the immediate withdrawal of the offending drug and then the administration of an antihistamine medicine. In severe allergic reactions, adrenaline and steroids may be used to save a life.
