The primary hallmark signs of malnutrition are unintentional weight loss, loss of muscle mass, and fatigue/weakness. However, malnutrition is a broad term that also includes conditions like obesity and specific micronutrient deficiencies.
Common signs and symptoms of malnutrition include:
unintentional weight loss – losing 5% to 10% or more of weight over 3 to 6 months is one of the main 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.
The six characteristics put forward include insufficient energy intake, weight loss, loss of subcutaneous fat, localized or generalized fluid accumulation that may mask weight loss, loss of muscle mass, and diminished functional status as measured by hand grip strength (Table 2).
Other symptoms of malnutrition include:
Albumin and transferrin levels were recommended as markers to identify malnutrition and became highly utilized as a metabolic assessment of nutrition. In 1979, albumin and transferrin were used as 2 biomarkers for “instant nutrition assessment.”
The IPC Acute Malnutrition Scale is a five-phase scale of increasing severity: Phase 1: Acceptable; Phase 2: Alert; Phase 3: Serious; Phase 4: Critical; Phase 5: Extremely Critical. Each phase is characterized by a certain prevalence of acute malnutrition.
In many countries, and even within households, these three forms of malnutrition (undernutrition, hidden hunger and overweight) co-exist in what is known as the triple burden of malnutrition. This burden is only expected to grow and threatens children's survival, growth and development.
Nutrient deficiencies and muscle breakdown
Another serious side effect of undereating is the development of nutrient deficiencies, which can lead to health conditions like anemia (often a result of iron deficiency), cold intolerance, hair loss, skin problems, insomnia, bone issues, and a weakened immune system.
There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals. Undernutrition makes children in particular much more vulnerable to disease and death. Low weight-for-height is known as wasting.
Malnutrition Warning Signs
Lack of muscle mass. Swollen stomach (called Kwashiorkor) Fatigue and low energy levels. Lack of growth and low body weight (in children)
6 Signs of Nutrient Deficiency
Dietary changes and supplements
having a healthier, more balanced diet. eating "fortified" foods that contain extra nutrients. snacking between meals. having drinks that contain lots of calories.
Top Diet Red Flags
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.
Malnutrition encompasses both undernutrition (wasting, stunting, underweight) and overweight, obesity, and diet-related non-communicable diseases. In 2022, an estimated 149 million children under five were stunted, while 45 million suffered from wasting globally.
Signs and symptoms that a person may not be eating enough include:
You may feel sick to your stomach after eating just a few bites. Early satiety is usually a symptom of an underlying medical condition. If left untreated, it can lead to complications, including nutrient deficiencies and malnutrition.
Restricted eating, malnourishment, and excessive weight loss can lead to changes in our brain chemistry, resulting in increased symptoms of depression and anxiety (Centre for Clinical Interventions, 2018b). These changes in brain chemistry and poor mental health outcomes skew reality.
Common problems encountered in severe acute malnutrition include hypothermia, hypoglycaemia, severe dehydration and electrolyte disturbances, septic shock, severe anaemia and severe vitamin A deficiency.
Fortifying your foods to increase calories
You get calories in: protein foods. fats and oils. starchy foods (bread, potatoes, pasta, rice and breakfast cereals)
The F-75 liquid therapeutic diet is intended for the initial phase of treatment of children diagnosed with Severe Acute Malnutrition (SAM). It is intended to stabilize the child's metabolism and support rehydration.
What are the signs your body is in starvation mode?
under 18.5kg/m2 – you are considered underweight and possibly malnourished. 18.5 to 24.9kg/m2 – you are within a healthy weight range for young and middle-aged adults. 25.0 to 29.9kg/m2– you are considered overweight. over 30kg/m2 – you are considered obese.
