1. The basis of claim on the part of a party to a lawsuit or an insurance carrier. In litigation, loss may be expressed in monetary terms.
2. Destruction, degeneration, or the wasting of cells, tissues, organs, or capabilities.
central vision loss
Loss of the ability to see things directly in front of the eye, often occurring in patients with macular degeneration. The macula of the retina contains the greatest concentration of cone photoreceptors in the eye and is the location on the retina where vision is sharpest and colors are perceived with greatest clarity. When diseases like macular degeneration disturb the integrity of the macula, central vision loss occurs. A sudden loss of central vision is an ophthalmological emergency, requiring referral to a retinal specialist as soon as possible.
conductive hearing loss
Hearing loss due to any condition that prevents sound waves from being transmitted to the auditory receptors. It may result from wax obstructing the external auditory meatus, inflammation of the middle ear, ankylosis of the ear bones, or fixation of the footplate of the stirrup. Synonym: conduction deafness See: otosclerosis; Rinne test; Weber test
loss of consciousnessSyncope.
functional visual loss
A reduction in vision with no identifiable lesion of the visual pathways. It may be caused by an occult disease of the eye or of the optical centers in the brain. It may also occur in certain psychiatric disorders.
gravity-induced loss of consciousness Abbreviation: GLOC
The loss of consciousness due to positive gravity (G) forces. Certain aviation maneuvers produce increased downward force (that is, positive G) that is measured as a multiple of the gravitational constant. When these forces are of sufficient intensity, blood flow to the brain is diminished, which, if continued, leads to unconsciousness.
A decreased ability to perceive sounds as compared with what the individual or examiner would regard as normal. In the U.S., about 1 million school-age children and 25 million adults have some degree of hearing loss. See: audiogram; audiometry
insensible fluid lossInsensible loss.
A loss of body fluid that is not easily measured, e.g., the moisture released in exhalation and perspiration. The amount of fluid typically lost is about 200 mL a day. Insensible fluid losses increase in any disease or condition that increases diffusion of liquid from the skin or the lungs, e.g., in burns, climatic changes, fever, or heavy exercise. Synonym: insensible fluid loss
noise-induced hearing loss
Hearing loss from exposure to very loud sounds (over 85 dB). The loss is usually most profound at a frequency of 4000 Hz. Common causes include working with noisy machinery, listening to loud music, or discharging rifles, guns, or explosives. Wearing ear plugs or earmuffs may be preventive.
peripheral vision lossTunnel vision (1).
Miscarriage or stillbirth.
recurrent pregnancy loss Abbreviation: RPL
Three or more consecutive miscarriages that occur before the 20th week of gestation.
A measurable loss of body fluid, e.g., blood, diarrhea, urine, vomit. If sensible losses consistently exceed fluid intake, dehydration may result.
sensorineural hearing loss
Hearing loss from permanent or temporary damage to the sensory cells or nerve fibers of the inner ear.
sudden hearing loss
Hearing loss that occurs in 72 hr or less. It may be temporary or permanent. Some of the most common causes include cerumen impaction, medication toxicities, acute infections, ear trauma, Ménière's disease, and ischemia.
Loss of vitamin content in food products from oxidation or heating. Methods of preserving foods such as pickling, salting, curing, fermenting, and canning enhance vitamin loss. Vitamin C is esp. labile; up to 85% is lost in commercial canning and pasteurization. Vitamin B1 in wheat is lost through milling because the vitamin B1 wheat embryo is removed.
A measurable decline in body weight (BW) either intentionally or from malnutrition or illness. It is considered mild when 5% of BW is lost, moderate when 5-10% of BW is lost, and high when more than 10% of BW is lost.
Intentional weight loss achieved through dieting and/or exercise has significant health benefits for the overweight or obese. It reduces the risk of many common illnesses, including coronary artery disease, type 2 diabetes mellitus, hyperlipidemia, and hypertension. Unintentional weight loss, esp. of more than 10% of BW may be a marker of serious disease, such as AIDS, cancer, depression, hyperthyroidism, parasitosis, peptic ulceration, or food insecurity (starvation due to an inadequate food supply).

Patient discussion about bone loss
Q. is bone loss related to Arthritis?
A. It depends on the kind of arthritis. In some arthritic diseases there's local bone loss, and generalized bone loss (osteoporosis) may result from steroids used to treat arthritic diseases.

Q. is there is any relation between not enough acid and arthritis?is bone loss is another factor in this decease?
A. Do you refer to less of acid secretion in the stomach (hypochlorhydia)? If so, then sjogren syndrome is a disease that cause both lack of acid in the stomach (due to chronic inflammation of the stomach, called atrophic gastritis) and arthritis (sometimes osteoarthritis).
Bone loss (osteoporosis) is actually associated with LOWER risk for osteoarthritis, although it has its own detrimental effects, so one should treat osteoporosis (and prevent osteoarthritis in other ways).
Q. Is osteoporosis preventable? My mother had osteoporosis and I already have osteopenia which may lead to it. How can I prevent it??
A. Prevention of osteoporosis, in it's strict sense, is done mainly during childhood through early adulthood (third decade) - the years during which the peak bone density is determined. At older age, treatment of osteoporosis, apart from medications, include vitamin D and calcium supplementation, physical activity and avoiding smoking and excess alcohol consumption.More discussions about bone loss
There are also medications to treat osteoporosis, mainly from the bisphosphanate class. However, remember to consult your doctor before you make any change in your diet or start exercise program.
