The symptoms of CmRD are similar to the physical symptoms of malnutrition, as the disease arises due to the poor absorption of lipids and fat-soluble nutrients such as vitamin E. For this reason, the disease is likely to be underdiagnosed by physicians. Fat-soluble nutrients are essential for growth, development, and normal bodily function.
Small intestine : major site of absorption. Symptoms can manifest in a variety of ways and features might give a clue to the underlying condition. Symptoms can be intestinal or extra-intestinal - the former predominates in severe malabsorption. [citation needed] Diarrhoea, often steatorrhoea, is the most common feature. Watery, diurnal and ...
The stool may contain large chunks of fat and/or blood. Infants often present with gastrointestinal problems caused by the poor fat absorption, which also contributes to steatorrhea. Other features of this disorder may develop later in childhood and often impair the function of the nervous system.
Fatty-acid metabolism disorders result when both parents of the diagnosed subject are carriers of a defective gene. This is known as an autosomal recessive disorder. Two parts of a recessive gene are required to activate the disease. If only one part of the gene is present then the individual is only a carrier and shows no symptoms of the disease.
Short bowel syndrome (SBS, or simply short gut) is a rare malabsorption disorder caused by a lack of functional small intestine. [3] The primary symptom is diarrhea, which can result in dehydration, malnutrition, and weight loss. [1]
Vitamin E deficiency in humans is a very rare condition, occurring as a consequence of abnormalities in dietary fat absorption or metabolism rather than from a diet low in vitamin E. [1] Collectively the EARs, RDAs, AIs and ULs for vitamin E and other essential nutrients are referred to as Dietary Reference Intakes (DRIs). [1]
The signs and symptoms of micronutrient deficiencies depend on which micronutrient is lacking. [2] However, undernourished people are often thin and short, with very poor energy levels; and swelling in the legs and abdomen is also common. [1] [2] [50] People who are undernourished often get infections and frequently feel cold. [2]
A person may be underweight due to genetics, [7] [8] poor absorption of nutrients, increased metabolic rate or energy expenditure, lack of food (frequently due to poverty), low appetite, drugs that affect appetite, illness (physical or mental) or the eating disorder anorexia nervosa. [9] [10]
