Body Mass Index (BMI) provides objective criteria of size to enable an estimation to be made of an individual’s level or risk of morbidity and mortality. The BMI, which is derived from the extensive data held by life-insurance companies, is calculated by dividing a person’s weight by the square of his or her height (kilograms/ metres2). Acceptable BMIs range from 20 to 25 and any ?gure above 30 characterises obesity. The Index may be used (with some modi?cation) to assess children and adolescents. (See OBESITY.)

(BMI) the weight of a person (in kilograms) divided by the square of the height of that person (in metres): used as an indicator of whether or not a person is over- or underweight. For example, a person who is 1.7 m tall and weighs 65 kg has a BMI of 65/1.72 = 22.5. A BMI of between 20 and 25 is considered normal, between 25 and 30 is overweight, and greater than 30 indicates clinical *obesity. A BMI of less than 20 is considered underweight. A limitation of the BMI is that it cannot distinguish whether the weight is due to muscle or fat. BMI is not a valid metric in individuals with an altered body structure, as through physical disability. See also waist to hip ratio.

Ciliary Body

That part of the EYE that connects the iris and the choroid. The ciliary ring is next to the choroid; the ciliary processes comprise many ridges behind the iris, to which the lens’s suspensory ligament is attached; and the ciliary muscle contracts to change the curvature of the lens and so adjust the accommodation of the eye.... ciliary body

Carotid Body

A small reddish-brown structure measuring 5–7 × 2·5–4 millimetres, situated one on each side of the neck, where the carotid artery divides into the internal and external carotid arteries. Its main function is in controlling breathing so that an adequate supply of oxygen is maintained to the tissues of the body. Oxygen levels are controlled by a re?ex operating between the carotid body and the respiratory centre in the brain.... carotid body

Body Odour

A personal and social problem. Over-activity of the sweat glands. Offensive smell is caused by the action of bacteria on stale sweat. The purpose of antiperspirants is to reduce skin bacterial action on apocrine sweat. Almost all antiperspirants sold over the counter are made from aluminium salts which have been implicated in skin granulomas. Deodorants that bear labels describing contents as dangerous to the eyes, nose and mouth should be rejected.

Bowel and kidney function should be investigated, as body odour is not normally offensive when these organs are healthy. Zinc is a powerful deodorant – zinc and castor oil cream being a traditional combination of pharmacy. Key herbal agent is Thuja, but it is sometimes advisable to add to this an agent for liver and kidneys.

Barberry Tea For Body Health

Barberry tea is well known inAsia, Europe, Africa and America due to its medicinal properties. Nowadays, it is consumed worldwide as tincture, fluid extract or capsules. Barberry tea description Barberry is a shrub growing in gray-colored and tight thorny hedges, producing yellow flowers during spring and red berries in autumn. Its roots, bark and berries have been used for more than 2,500 years for a variety of health-promoting purposes. In ancient Egypt, barberry was mixed with fennel to fight plague. Nowadays, Barberry is available in the form of capsules, fluid extract and tincture. Barberry Tea is made of the dried roots and berries of barberry. Barberry tea brewing To prepare Barberry tea: steep 1 to 2 teaspoons of dried barberry root or 1 to 2 teaspoons of whole (or crushed berries) in about 2/3 of a cup of hot water for 10 to 15 minutes. Barberry Tea can be consumed three times, daily. Barberry tea benefits Barberry tea has proven its efficiency in treating:
  • inflammation due to bacterial ear, nose and throat infection
  • bacterial and viral forms of diarrhea
  • psoriasis
  • the function of the gallbladder
  • urinary tract infection
  • heartburn
  • candida
  • epilepsy
Barberry Tea may help stabilize blood pressure and normalize heart rhythm. Also, it has been claimed that Barberry Tea may help strengthen the immune system. Barberry tea side effects Studies conducted so far showed that Barberry tea should not be used beyond seven consecutive days, in order to avoid complications on excessive use of barberry. There have been cases when Barberry tea interacted with anti-coagulants, blood pressure medication and antibiotics, causing side effects. Pregnant, nursing women, and nursing infants also should avoid drinking this tea.

Body Contour Surgery

Surgery performed to remove excess fat, skin, or both, from various parts of the body, especially the abdomen, thighs, and buttocks. Abdominal wall reduction, also known as abdominoplasty, involves removing excess skin and fat from the abdomen. With all of these procedures there is a risk of complications, and the wound may become infected.

In suction lipectomy (liposuction), a rigid hollow tube is inserted through a small skin incision and use to break up large areas of fat, which can then be sucked out through the instrument.

Minor irregularities and dimpling of the skin commonly occur after surgery.... body contour surgery

Tissues Of The Body

The simple elements from which the various parts and organs are found to be built. All the body originates from the union of a pair of CELLS, but as growth proceeds the new cells produced from these form tissues of varying character and complexity. It is customary to divide the tissues into ?ve groups:

Epithelial tissues, including the cells covering the skin, those lining the alimentary canal, those forming the secretions of internal organs. (See EPITHELIUM.)

Connective tissues, including ?brous tissue, fat, bone, cartilage. (See under these headings.)

Muscular tissues (see MUSCLE).

Nervous tissues (see NERVE).

Wandering corpuscles of the BLOOD and LYMPH. Many of the organs are formed of a single

one of these tissues, or of one with a very slight admixture of another, such as cartilage, or white ?brous tissue. Other parts of the body that are widely distributed are very simple in structure and consist of two or more simple tissues in varying proportion. Such are blood vessels (see ARTERIES; VEINS), lymphatic vessels (see LYMPHATICS), lymphatic glands (see GLAND), SEROUS MEMBRANES, synovial membranes (see JOINTS), mucous membranes (see MUCOUS MEMBRANE), secreting glands (see GLAND; SALIVARY GLANDS; THYROID GLAND) and SKIN.

The structure of the more complex organs of the body is dealt with under the heading of each organ.... tissues of the body

Eyes – Foreign Body

From coal dust, insects, pollen, etc.

Symptoms: blinking, watering, acute discomfort. Sensation of grit in the eye does not always imply foreign body, but symptoms of conjunctivitis or keratitis. Automatic blinking is sometimes enough to clear offending object.

Treatment. External. Evert lid and remove. Swab out with dilute Witch Hazel on cotton wool. Inject one drop Castor oil, (also good for scratched cornea), Aloe Vera gel or juice. Fenugreek seed puree. Juice of Houseleek and dairy cream.

Difficult case. Removal of particles of iron or dust, apply mucilage of Slippery Elm powder to eye – patient lying on his back, a second person injecting it into corner of eye, the patient moving eye in opposite direction. Safe and healing. Clean eye and bathe with warm milk.

Referral to consultant ophthalmologist. ... eyes – foreign body

Eye, Foreign Body In

Any material on the surface of the eye or under the lid, or an object that penetrates the eyeball.

A foreign body may cause irritation, redness, increased tear production, and blepharospasm. In some cases, a foreign body left in the eye may cause a reaction that results in permanent loss of sight in both eyes.

Foreign bodies on or in the conjunctiva can usually be flushed out with water.

However, medical attention is needed if the object has penetrated the eyeball.

Dropping the dye fluorescein into the eye reveals corneal abrasions or sites of penetration.

Ultrasound scanning or an X-ray of the eye may also be performed.

Local anaesthetic eye-drops may be applied and a spatula used to remove an object from the cornea.

The eye may then be covered with a patch.

Antibiotic drugs may also be prescribed.... eye, foreign body in

Glycaemic Index

(GI) a ranking system measuring the effect carbohydrate (CHO) ingestion has on blood glucose levels. Glucose is used as the standard reference value (50 g glucose has a GI of 100). A portion of food containing 50 g CHO is ingested and the effect on blood glucose levels measured over a three-hour period and compared with the effect of 50 g of glucose. Foods with a low GI (<60), such as apples, yoghurt, and beans, are slowly absorbed, causing a lower and more prolonged increase in blood glucose levels, than foods with a high GI (>70), e.g. white bread, white rice, and potatoes. Low GI foods help with diabetes control and may be beneficial in the treatment of *polycystic ovary syndrome. The glycaemic load (GL) also takes into account the amount of food that is eaten: GL = (g CHO in food portion eaten × GI)/100.... glycaemic index
