Sinusitis is an inflammation, or swelling, of the tissue lining the sinuses. Normally, sinuses are filled with air, but when sinuses become blocked and filled with fluid, germs (bacteria, viruses, and fungi) can grow and cause an infection.

Conditions that can cause sinus blockage include the common cold, allergic rhinitis (swelling of the lining of the nose), nasal polyps (small growths in the lining of the nose), or a deviated septum (a shift in the nasal cavity).

Allergies occur when the body's immune system reacts to a particular substance as though it's harmful. It's not clear why this happens, but most people affected have a family history of allergies or have closely related conditions, such as asthma or eczema.

The number of people with allergies is increasing every year. The reasons for this are not understood, but 1 of the main theories is it's the result of living in a cleaner, germ-free environment, which reduces the number of germs our immune system has to deal with. It's thought this may cause it to overreact when it comes into contact with harmless substances.

Arthritis is an inflammation of the joints that is characterized by swelling, heat, and pain. Nearly 300,000 children in the United States have some sort of arthritis. Arthritis can be short-term — lasting for just a few weeks or months, then going away forever — or it can be chronic and last for months or years. In rare cases, it can last a lifetime

The thyroid, located at the base of the neck, is a small endocrine gland that regulates specific types of hormones.

The hormones produced by the thyroid control our metabolism and how our body uses energy. These hormones affect every organ — influencing the heart rate, digestion, weight, energy levels and mood, among others.

Because it’s such a powerful force within the body, optimal thyroid function is a key component for overall health. The thyroid is often misunderstood and related disorders go unrecognized

Thyroid is one of the body’s most important glands. Thyroid dysfunction is one of the most common clinical conditions seen frequently. Thyroid function influences energy formation, circulation, immune function, the metabolism of all the organs, blood sugar regulation, emotional stability, and hormonal balance.

Thyroid is a butterfly shaped gland located in the neck on either side of the voice box that controls the overall metabolic rate of the body.

Fibroids are non-cancerous or benign growths that develop in the uterus. As many as 30 percent of women have one or more of these tumors, which range in size from as small as a pea to as large as a melon.

Most women with fibroids have no symptoms and don't need treatment. But if symptoms occur, you should seek medical attention.

The tonsils are two small glands that sit on either side of the throat. In young children, they help to fight germs and act as a barrier against infection.

When the tonsils become infected, they isolate the infection and stop it spreading further into the body. As a child's immune system develops and gets stronger, the tonsils become less important and usually shrink. In most people, the body is able to fight infection without the tonsils

Fibroids can grow in different parts of the uterus the pear-shaped organ located between the bladder and rectum.

The uterine walls are composed of muscle, allowing it to expand enormously during pregnancy. Within the uterus is a central cavity in which the fetus develops.

Fibroids are round muscle growths that develop within a woman's uterus, also known as the womb, which is a pear-shaped organ located between the bladder and rectum.

Fibroids are almost always benign, meaning that they are non-cancerous. Fibroids vary in size, ranging from as small as a pea to as large as a melon. They are also called leiomyomas or myomas.

The terms eczema and dermatitis are now used synonymously. They refer to a distinctive reaction pattern of the skin showing a combination of signs which depend on the duration of rash and type of eczema.

There are several types of eczema, which affect children and adults, and have different causes. The two most common forms are atopic dermatitis (Exogenous) and contact dermatitis (Endogenous).
