Under what conditions is nitrogen balance positive or negative?
Nitrogen balance (NB), or nitrogen equilibrium, occurs when nitrogen intake equals nitrogen output (NB = 0). A positive NB or anabolic state exists when nitrogen intake exceeds nitrogen output.
What condition would bring about positive nitrogen balance quizlet?
Positive nitrogen balance is when protein intake excees protein loss. Individuals growing or recovering, atheletes, pregnant women etc. In negative balance protein losses exceed protein intake.
What are some examples of positive nitrogen balance?
During growth, pregnancy, lactation, and recovery from convalescence, the body is in positive nitrogen balance since it is retaining nitrogen for the purpose of synthesizing new protein tissues. During dietary deprivation, most illnesses, and certain types of stress, the body loses nitrogen and is in negative balance.
What condition produces negative nitrogen balance?
A negative nitrogen balance may occur during physical or emotional stress, starvation, when an individual is on a very low calorie diet, or when the quality of protein is poor (e.g. when the diet is lacking essential amino acids).
What is the difference between positive and negative nitrogen balance?
A negative nitrogen balance occurs when more protein is used by the body than is taken in. A positive nitrogen balance implies a net gain of protein in the body. Negative nitrogen balance can be caused by such factors as malnutrition, debilitating diseases, blood loss, and glucocorticoids.
Which amino acid causes negative nitrogen balance?
Regardless of the absolute insulin concentration, this drop causes an increase in the free fatty acids and the branched-chain amino acids, together with a decrease in the concentrations of alanine and glycine (threonine) in the blood and a negative nitrogen balance.
What condition would bring about a negative nitrogen balance quizlet?
Which of the following conditions would result in negative nitrogen balance? kidney disease. is a disease of severely deficient protein intake.
What is a positive nitrogen balance and what kind of person has this condition quizlet?
Positive nitrogen balance is when lost nitrogen exceeds nitrogen consumed with food. Positive nitrogen balance occurs when a person is always in a state of hunger. You just studied 22 terms!
What is short note kwashiorkor?
Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema).
When nitrogen consumption is greater than nitrogen excretion a person is in positive nitrogen balance?
A person is said to be in nitrogen balance when the nitrogen input equals the amount of nitrogen used and excreted (Table 6.4. 1). A person is in negative nitrogen balance when the amount of excreted nitrogen is greater than that consumed, meaning that the body is breaking down more protein to meet its demands.
What is marasmus and kwashiorkor?
Marasmus: Severe weight loss and muscle wasting due to lack of nutrition and calories. Kwashiorkor: Swelling or edema due to water retention from lack of protein. Marasmic-kwashiorkor: A combination of muscle wasting and bilateral edema.
What is difference between marasmus and kwashiorkor?
Kwashiorkor, a severe protein deficiency, causes fluid retention and a protruding abdomen. On the other hand, the condition marasmus, which results from severe calorie deficiency, leads to wasting and significant fat and muscle loss (5). Undernutrition can also result in micronutrient deficiencies.
What causes marasmus?
Marasmus always results from a negative energy balance. The imbalance can result from a decreased energy intake, an increased loss of ingested calories (eg, emesis, diarrhea, burns), an increased energy expenditure, or combinations of these factors, such as is observed in acute or chronic diseases.
What is pellagra disease?
Pellagra is a disease that occurs when a person does not get enough niacin (one of the B complex vitamins) or tryptophan (an amino acid).
Is a child with marasmus is in negative nitrogen balance?

What are the 4 types of malnutrition?
There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals.
What is kwashiorkor caused by?
The main cause of kwashiorkor is not eating enough protein or other essential vitamins and minerals. It's most common in developing countries with a limited food supply, poor hygiene, and a lack of education about the importance of giving babies and children an adequate diet.
What is kwashiorkor and marasmus?
Kwashiorkor, a severe protein deficiency, causes fluid retention and a protruding abdomen. On the other hand, the condition marasmus, which results from severe calorie deficiency, leads to wasting and significant fat and muscle loss (5). Undernutrition can also result in micronutrient deficiencies.
What causes kwashiorkor and marasmus?
Like marasmus, kwashiorkor is a type of malnutrition caused by protein deficiency. It mainly occurs in children who are weaning off breast milk, while marasmus can develop in infants. If your diet has a lot of carbohydrates and very little proteins, you may develop kwashiorkor.
What happens in beri beri?
Beriberi is a deficiency of thiamin, more commonly known as vitamin B1. Your body needs thiamin to break down and digest the foods you eat, to keep your metabolism going, and help your muscles and nervous system do their jobs effectively. Beriberi can affect the cardiovascular system or central nervous system.
What is difference between kwashiorkor and marasmus?
Marasmus is severe malnutrition characterized by energy deficiency. Kwashiorkor is a protein deficiency disorder with adequate energy intake, whereas Marasmus is inadequate energy intake including proteins.

What is Wernicke Korsakoff disease?
Definition. Wernicke's encephalopathy is a degenerative brain disorder caused by the lack of thiamine (vitamin B1). It may result from alcohol abuse, dietary deficiencies, prolonged vomiting, eating disorders, or the effects of chemotherapy. B1 deficiency causes damage to the brain's thalamus and hypothalamus.

What is the difference between Wernicke encephalopathy and Korsakoff syndrome?
Wernicke encephalopathy causes brain damage in lower parts of the brain called the thalamus and hypothalamus. Korsakoff syndrome results from permanent damage to areas of the brain involved with memory.

What is the difference between Broca’s and Wernicke’s area?
Essentially, Wernicke's area works to make sure the language makes sense, whilst Broca's area helps to ensure the language is produced in a fluent way. This understanding of language was later expanded upon by neurologist Norman Geschwind, who proposed what would be known as the Wernicke-Geschwind model.
