### condition:

Deficiency
* Deficiencies affect ability
  - bone growth
  - development
  - fetal development
  - functions
  - immune responses
  - life
  - skeletal development
  - weight
* Deficiencies are caused by diets
  - inability
  - lack
  - shortages
  - common in lactating pets
  - more common among women with regular menstrual periods
  - most common in low-income and teenage pregnant women
  - pale leaf color of youn g leaves followed by yellowing of leaves and large veins
  - rare and usually occur in association with lack of thiamine and nicotinic acid
  - rare, but can lead to uncontrolled bleeding
  - shortages in street capacity, which prevent efficient traffic flow
  - very rare, as vitamin E is abundant in foods
  - can cause poor growth, condition, and egg binding
* Deficiencies can have different symptoms
* Deficiencies can lead to blindness and poor reproduction
  - congenital malformations and possible mental retardation in babies
  - impaired vision, poor memory and learning difficulties
  - low sperm count, reduced libido and impotency
* Deficiencies can occur if the diet is inadequate as in the elderly
  - in countries where the soil is depleted
  - reduce yields, cause yellowing of the leaves and stunt growth
  - can, with time, cause serious disease, especially in cats
* Deficiencies cause birth defects
  - death
  - deficiencies
  - die back of the shoot tips, and terminal leaves develop brown spots
  - diseases
  - easily bruising skin, pyorrhoea, spongy bleeding gums, conditions like scurvy
  - fatigue
  - health problems
  - membrane defects seen as poor skin and feather condition
  - neurological problems
* Deficiencies cause premature death
  - leaf death
  - reductions
* Deficiencies cause serious health problems
  - similar symptoms
  - the baby's growth to slow and can lead to miscarriage or birth defects
  - thyroid problems
* Deficiencies create disease and infection
* Deficiencies decrease arsenic excretion
* Deficiencies decrease urinary arsenic excretion
  - disrupt biological functions
* Deficiencies disrupt essential biological functions
  - exhibit slow growing, weak and stunted plants with light green to yellow older leaves
* Deficiencies have certain specific symptoms
  - considerable trouble
  - distinct effects
  - dramatic effects
* Deficiencies impair ability
  - involve energy and proteins, as well as vitamins and minerals
* Deficiencies lead to abnormalities
  - bleeding problems of various types
  - considerable damage
  - degeneration
  - disorder
  - irreversible damage
  - metabolic abnormalities
  - muscle diseases
  - neurological disorder
  - permanent damage
  - white muscle diseases
  - occur at ages
* Deficiencies occur in infants
  - premature infants
  - often occur with alcoholism, but are otherwise rare
  - primarily causes venous thrombosis
  - produce symptoms
* Deficiencies require care
  - treatments
  - result directly in apple fruit disorders, but also reduce calcium uptake
* Deficiencies result in health problems
  - immunity
  - impairment
  - nerve problems
  - reproductive problems
* Deficiencies result in serious health problems
  - skin disorders and muscle pains
  - visual impairment
  - take places
  - trigger imbalances
  - typically develop in the elderly, alcoholics, cancer patients, and some food faddists
* Most deficiencies affect bone growth
* Most deficiencies cause birth defects
* Most deficiencies decrease urinary arsenic excretion
* Most deficiencies lead to diseases
* Most deficiencies occur in infants
* Some deficiencies affect children
  - geckos
  - young lambs
* Some deficiencies cause anemia
  - embryo mortality
  - tongue inflammation
  - contribute to osteoporosises
* Some deficiencies decrease intestinal absorption
  - calcium absorption
* Some deficiencies lead to deficiency anemia
  - lung inflammation
* Some deficiencies limit fat metabolism
  - manifest in mental disease
  - result in diseases
* affects hearing and vision.
* aggravates malabsorption.
* can be the cause of numerous problems, including mental and physical exhaustion.
* causes cracks in the mouth and outer lip, skin, mouth, and eye troubles
  - hair loss and loss of appetite and depression
* causes inflammation of the lining of the mouth and skin
  - skin, vagina, rectum and mouth, as well as mental slowing
  - irritability of the nervous system
* causes reduced growth rates and lesions of the skin on the lower extremities
  - growth, size and quality of all plants
  - scurvy in humans, and somewhat similar symptoms in other animals
  - stunting of new growth in stems, flowers and roots
* leads to beriberi in humans and to polyneuritis in birds
  - beriberi, a disease of the heart and nervous system
  - cirrhosis of the liver
  - cretinism
  - megaloblastic anaemia
  - pernicious anaemia
  - poor vision in dim light and eventually to blindness
* occurs as a result of poor dietary intake or inadequate absorption
  - in the form of iron deficiency anemia
  - with malnutrition and in areas where the soil has very low selenium levels
* shows up as emaciated and anemic animals.
