What are the signs and symptoms of protein-energy malnutrition? (2023)

What are 4 signs of malnutrition?

a low body weight – people with a body mass index (BMI) under 18.5 are at risk of being malnourished (use the BMI calculator to work out your BMI) a lack of interest in eating and drinking. feeling tired all the time. feeling weak.

Symptoms of Protein Energy Malnutrition

Apathy and irritability. The patient becomes weak and inefficient. Impaired cognition and consciousness. Temporary lactose deficiency.

Introduction. According to World Health Organization, protein energy malnutrition (PEM) refers to “an imbalance between the supply of protein and energy and the body's demand for them to ensure optimal growth and function”.[1] It is a major public health problem in India.

The term malnutrition addresses 3 broad groups of conditions: undernutrition, which includes wasting (low weight-for-height), stunting (low height-for-age) and underweight (low weight-for-age);

Some people may consume a lot of calories, but not enough vitamins and minerals. In these cases, the effects of malnutrition may be less obvious. People may be overweight from macronutrient overnutrition but may have symptoms of anemia — weakness, faintness and fatigue — due to the lack of minerals or vitamins.

Weakness and Fatigue

And over time, a lack of protein can make you lose muscle mass, which in turn cuts your strength, makes it harder to keep your balance, and slows your metabolism. It can also lead to anemia, when your cells don't get enough oxygen, which makes you tired.

Treatment may involve: dietary changes, such as eating foods high in energy and nutrients. support for families to help them manage factors affecting the child's nutritional intake. treatment for any underlying medical conditions causing malnutrition.

What happens to your body when you are malnourished?

Malnutrition can result in unplanned weight loss, a low body mass index (BMI) and vitamin and mineral deficiencies. This can leave you feeling tired, weak and affect your ability to recover from an illness. In the UK, evidence suggests that: 29% of people admitted to hospital are malnourished.

Protein-energy malnutrition is associated with an increased risk of liver cirrhosis complications, including ascites, variceal bleeding, hepatic encephalopathy, and hepatorenal syndrome.

Protein-calorie malnutrition is separated into two forms, kwashiorkor and marasmus. Kwashiorkor is a state of acute, severe protein-calorie malnutrition resulting in edema and hair changes, often accompanied by encephalopathy. Marasmus is the chronic form of this disorder and causes apathy and growth failure.

Milk-based formulas are the treatment of choice. At the beginning of dietary treatment, patients should be fed ad libitum. After 1 week, intake rates should approach 175 kcal/kg and 4 g/kg of protein for children and 60 kcal/kg and 2 g/kg of protein for adults. A daily multivitamin should also be added.

living alone and being socially isolated. having limited knowledge about nutrition or cooking. alcohol or drug dependency. low income or poverty.

Poverty is the number one cause of malnutrition in developing countries. Often times, families living in poverty lack access to fresh fruits and vegetables.

The recovery rate for oedematous malnutrition was 57.6% (95% CI 52.9% to 62.2%) whereas the recovery rate for non-oedematous malnutrition was 63.8% (95% CI 61.1% to 66.5%). The median time to recovery was 16 days (IQR=11–28).

PEM is caused by starvation. It is the disease that develops when protein intake or energy intake, or both, chronically fail to meet the body's requirements for these nutrients. PEM has always been a common disease, and humans have adaptive mechanisms for slowing and, in most cases, arresting its progress.

The nutrition-focused physical examination (NFPE) is an essential component for diagnosing malnutrition. Focusing on general characteristics such as edema, muscle wasting and subcutaneous fat loss to specific micronutrient related deficiencies, the NFPE is very sensitive for assessing nutritional status.

Protein-energy malnutrition is diagnosed clinically based on the history and examination including measurement of height, weight, and body mass index (BMI). Blood tests will typically show anaemia, low serum protein and albumin levels, and often liver function abnormalities.

When should you go to the hospital for malnutrition?

A few key signs of malnutrition indicate that it is time for a person to seek care from a doctor. These signs include: unexplained, unintentional weight loss of more than 5% in the last 3–6 months. presence of other malnutrition symptoms.

However, people who have voluntarily stopped eating to participate in hunger strikes have died after 45–61 days , which suggests that a person would be unlikely to survive for 3 months. The body needs the nutrients in food to survive.

Obesity-the most prevalent form of malnutrition.

The most helpful laboratory studies in assessing malnutrition in a child are hematological studies and laboratory studies evaluating protein status: Hematological studies should include a CBC count with RBC indices and a peripheral smear.

General symptoms of malnutrition include feeling tired and irritable, bone or joint pain, slow wound healing, and infections.

Kwashiorkor, also known as “edematous malnutrition” because of its association with edema (fluid retention), is a nutritional disorder most often seen in regions experiencing famine. It is a form of malnutrition caused by a lack of protein in the diet.

You can become deficient in protein if you don't eat enough food sources. Severe protein deficiency is called kwashiorkor. This condition is more common in low income countries where people don't have enough to eat. Some people do not consume enough protein in their diet, possibly due to dietary choices or aversions.

The Recommended Dietary Allowance or “RDA” for protein is 0.8 grams per kilogram body weight. So to calculate this, take your weight in pounds, divide it by 2.2 (to get your body weight in kilograms) then multiply that number by 0.8.

Can malnutrition be reversed?

Those who are particularly susceptible to malnutrition include older adults and adults experiencing a chronic health illness such as cancer or arthritis. The good news is that malnutrition can be prevented and the effects can be reversed with proper nutritional restoration.

BRAIN: Nutrient deficiencies may speed up the rate at which your brain loses neurons, which can impair your speech, coordination, and memory. 10.

To understand the reasoning for this, it is important to know that in malnourishment, the rounded abdomen is not due to fat accumulation. Instead, the water retention and fluid buildup in the body cause the abdomen to expand. This results in a bloated, distended stomach or abdominal area.

The causes of malnutrition are at different levels. The immediate causes are inadequate dietary intake and disease. Inadequate dietary intake and diseases are caused by food insecurity, inadequate care for women and children, insufficient health services, and unsanitary environments.

Physical Examination. Your weight is the most obvious indicator of malnutrition. If you have lost weight, your current weight will be compared to your previous weights. Your body mass index (BMI) will also be determined and compared to the normal BMI range for a person of your height and age.

Malnutrition may lead to cardiovascular diseases such as cardiomyopathy, heart failure, cardiac arrhythmia, and in some cases sudden death during childhood (1–4).

Structurally malnutrition results in tissue damage, growth retardation, disorderly differentiation, reduction in synapses and synaptic neurotransmitters, delayed myelination and reduced overall development of dendritic arborization of the developing brain.

Marasmic kwashiorkor (marked protein deficiency and marked calorie insufficiency signs present, sometimes referred to as the most severe form of malnutrition)

Mild or moderate PEM are best judged by anthropometry; regular weighing, for monitoring growth, may be a useful control strategy. Because infections play such an important role in PEM, three practical approaches-immunization, deworming of children, and oral rehydration therapy for diarrhea--are discussed.

Protein misfolding is believed to be the primary cause of Alzheimer's disease, Parkinson's disease, Huntington's disease, Creutzfeldt-Jakob disease, cystic fibrosis, Gaucher's disease and many other degenerative and neurodegenerative disorders.

What prevents protein-energy malnutrition?

Preventive measures include continuous nutritional counseling, optimizing dietary nutrient intake, renal replacement therapy, and management of the different comorbidities (metabolic acidosis, diabetes mellitus, congestive heart failure, depression) [50].

There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals.

Malnutrition can result in unplanned weight loss, a low body mass index (BMI) and vitamin and mineral deficiencies. This can leave you feeling tired, weak and affect your ability to recover from an illness. In the UK, evidence suggests that: 29% of people admitted to hospital are malnourished.

Symptoms. Malnourished children may be short for their age, thin or bloated, listless and have weakened immune systems. Nutritional disorders can affect any system in the body and the senses of sight, taste and smell. They may also produce anxiety, changes in mood and other psychiatric symptoms.

The most helpful laboratory studies in assessing malnutrition in a child are hematological studies and laboratory studies evaluating protein status: Hematological studies should include a CBC count with RBC indices and a peripheral smear.

However, people who have voluntarily stopped eating to participate in hunger strikes have died after 45–61 days , which suggests that a person would be unlikely to survive for 3 months. The body needs the nutrients in food to survive.

How is malnutrition diagnosed? Physical observation and a history of your diet and health conditions are often enough to diagnose protein-energy undernutrition or overnutrition. Healthcare providers may measure your BMI or measure a child's arm circumference to help understand the extent of the problem.

How long does it take to recover from malnutrition?

The recovery rate for oedematous malnutrition was 57.6% (95% CI 52.9% to 62.2%) whereas the recovery rate for non-oedematous malnutrition was 63.8% (95% CI 61.1% to 66.5%). The median time to recovery was 16 days (IQR=11–28).

And over time, a lack of protein can make you lose muscle mass, which in turn cuts your strength, makes it harder to keep your balance, and slows your metabolism. It can also lead to anemia, when your cells don't get enough oxygen, which makes you tired.

Malnutrition can cause permanent, widespread damage to a child's growth, development and well-being. Stunting in the first 1,000 days is associated with poorer performance in school, both because malnutrition affects brain development, and also because malnourished children are more likely to get sick and miss school.

Learning problems that could lead to lower test scores and more absences from school. Reduced immunity — leading to the risk of contracting more infectious diseases.
