Insomnia

Sleep is as essential to us as food, air and water. Sometime in your life you may have difficulty sleeping - many people do. Anyone can suffer from insomnia, although sleeping problems are more common among women (especially menopausal), the ill, the elderly, smokers, and alcoholics. Sleep problems are, however, surprisingly common among young people. While it is not an illness and is in no way life-threatening, insomnia can be very distressing, frustrating, exhausting, depressing and at worst it can make you feel like you're going crazy.

Diabetes

Diabetes mellitus is a metabolic disorder characterized by hyperglycemia (high glucose blood sugar), among other signs. The World Health Organization recognizes three main forms of diabetes: type 1, type 2 and gestational diabetes (or type 3, occurring during pregnancy) [1], although these share signs and symptoms but have different causes and population distributions. They are not a single disease or condition. Type 1 is generally due to autoimmune destruction of the insulin-producing cells - pancreatic beta cells - while type 2 is characterized by tissue wide insulin resistance and varies widely. Gestational diabetes is due to a poorly understood interaction between fetal needs and maternal metabolic controls. Type 2 sometimes progresses to loss of beta cell function as well.

Migraine

Migraine is a painful neurological condition, of which the most common symptom is an intense and disabling episodic headache. Migraine headaches are usually characterized by severe pain on one or both sides of the head. Absent serious head injuries, stroke, and tumors, the recurring severity of the pain indicates a vascular headache rather than a tension headache. Migraines are often accompanied by photophobia (hypersensitivity to light), phonophobia (hypersensitivity to sound) and nausea. The word migraine is French in origin and comes from the Greek hemicrania, as does the Old English term megrim. Literally, hemicrania means "only half the head."

Rheumatoid Arthritis

Rheumatoid arthritis (RA) is traditionally considered a chronic, inflammatory autoimmune disorder that causes the immune system to attack the joints. It is a disabling and painful inflammatory condition, which can lead to substantial loss of mobility due to pain and joint destruction. RA is a systemic disease, often affecting extra-articular tissues throughout the body including the skin, blood vessels, heart, lungs, and muscles.

Attention-Deficit Hyperactivity Disorder (ADHD)

Attention-Deficit/Hyperactivity Disorder (ADHD) (sometimes referred to as ADD for those without hyperactivity) is thought to be a neurological disorder, always present from childhood, which manifests itself with symptoms such as hyperactivity, forgetfulness, poor impulse control, and distractibility.[1] In neurological pathology, ADHD is currently considered to be a chronic syndrome for which no medical cure is available. ADHD is believed to affect between 3-5% of the United States population, including both children and adults.

Breast Cancer

Breast cancer is a cancer of the breast tissue. Worldwide, it is the most common form of cancer in females - affecting, at some time in their lives, approximately one out of nine to one out of thirteen women who reach age ninety in the Western world. It is the second most fatal cancer in women (after lung cancer), and the number of cases has significantly increased since the 1970s, a phenomenon partly blamed on modern lifestyles in the Western world. Because the breast is composed of identical tissues in males and females, breast cancer can also occur in males, although cases of male breast cancer account for less than one percent of the total.

Asthma

Asthma is a chronic disease of the respiratory system in which the airway occasionally constricts, becomes inflamed, and is lined with excessive amounts of mucus, often in response to one or more triggers. These acute episodes may be triggered by such things as exposure to an environmental stimulant (or allergen), cold air, exercise or exertion, or emotional stress. In children, the most common triggers are viral illnesses such as those that cause the common cold. This airway narrowing causes symptoms such as wheezing, shortness of breath, chest tightness, and coughing, which respond to bronchodilators. Between episodes, most patients feel fine.

Bipolar Disorder

Bipolar Disorder is an affective mood disorder that manifests itself in a myriad of symptoms the most common of which are extreme oscillations between mania and depression over various time frames in each individual. Bipolar Disorder is commonly categorised as either Type I, where a patient suffers from severe mania and psychosis, or Type II, in which the patient generally only experiences hypomania - a form of mania more manageable on a day to day basis, in addition to long bouts of depression. Because there is so much variation in the severity and nature of mood-related problems, the concept of a bipolar spectrum of subtypes is often employed, and sometimes the concept of a continuum of mood variation merging in to the 'normal' range.

Acid Reflux

Gastroesophageal Reflux Disease (GERD; or GORD when spelling oesophageal, the BE form) is defined as chronic symptoms or mucosal damage produced by the abnormal reflux of gastric contents into the esophagus.This is commonly due to transient or permanent changes in the barrier between the esophagus and the stomach. This can be due to incompetence of the lower esophageal sphincter (LES), transient LES relaxation, impaired expulsion of gastric reflux from the esophagus, or association with a hiatal hernia.

High Cholesterol

Hypercholesterolemia (literally: high blood cholesterol) is the presence of high levels of cholesterol in the blood. It is not a disease but a metabolic derangement that can be secondary to many diseases and can contribute to many forms of disease, most notably cardiovascular disease. It is closely related to the terms "hyperlipidemia" (elevated levels of lipids) and "hyperlipoproteinemia" (elevated levels of lipoproteins).
