Top 10 Most Common Illnesses: Symptoms, Causes and Treatments

Allergies are an immune response triggered by allergens, a normally harmful substance. People with allergies have a particularly sensitive immune system that reacts when they come into contact with allergens. The best way to treat allergies is to eliminate or avoid the cause. When unavoidable, some lifestyle changes can reduce allergy symptoms.

For example, if you're allergic to dust mites, make an effort to keep your room clean and dust-free by vacuuming, dusting, and washing bedding frequently. For pollen allergies, avoid being outside when pollen levels are high and keep room windows closed. Some allergies go away with age, but others last a lifetime. Colds and influenza (flu) are the most common illnesses among college students. Cluster headache affects a specific point on the head, often the eye, and is characterized by sharp, penetrating pain.

Migraines and tension headaches are much more common. In fact, recent studies have demonstrated a connection between low levels of serotonin and so-called “tension” headaches. The cause of a headache is often difficult to reach. Even if your head seems to be pounding hard for no reason, there's always an explanation for the pain.

To find out the cause of your headaches, keep a record. Write down the date and time each headache starts and ends, the location of the pain, the nature and intensity of the pain, and any factors that seem to trigger it (diet, stress, menstrual cycle, medications, etc.). Mononucleosis is a disease caused by the Epstein-Barr virus (EBV), which is transmitted through saliva. Coronary artery disease (CAD) occurs when the arteries that supply blood to the heart become clogged or narrowed. This can happen because of the build-up of plaque (a fatty substance) in the artery walls.

Untreated CAD can cause chest pain, heart failure, and arrhythmias. Heart disease is more common in people with obesity and is also linked to poor diet, lack of physical activity, high cholesterol and high blood pressure (hypertension). However, there are things you can do to lower your risk of developing heart disease, such as following a healthy diet and exercising regularly. Chronic obstructive pulmonary disease (COPD) is a condition that makes it difficult to breathe. The main symptom of COPD is shortness of breath, which can worsen over time and make daily activities very difficult.

COPD is caused by a combination of factors, such as smoking, exposure to irritants such as chemicals, genetics, and lung infections. Asthma and Lung UK estimates that COPD affects more than 1.2 million people in the UK.

Type 1 diabetes, also known as juvenile diabetes, is an autoimmune disease that occurs when the body's immune system attacks and destroys insulin-producing cells in the pancreas. Type 2 diabetes is a condition that develops when the body becomes resistant to insulin or when the pancreas doesn't produce enough insulin. People with diabetes often have to take medications to control their blood sugar levels. In some cases they may also need to inject insulin.

Diabetes can lead to serious complications including heart disease, stroke, kidney failure and blindness. However with the right treatment many people with diabetes can live long and healthy lives. Patient's online services are now available in the U. S. UU.
