Types of Malnutrition
Malnutrition happens when your body doesn’t receive the right balance of nutrients it needs to stay healthy and perform properly. This imbalance can cause a range of issues such as unintentional weight loss, constant tiredness, and stunted growth.
There are several reasons why malnutrition may develop. These include not eating enough food, lacking access to nutritious meals, struggling with an eating disorder, or having a medical condition that interferes with how your body absorbs vital nutrients. Each of these factors can prevent your body from getting the nourishment it needs to thrive.
Types of Malnutrition
Malnutrition can be categorized according to its severity, underlying causes, and individual manifestations. In order to create effective treatment and management plans, healthcare providers must be able to identify these types.
Stunting in Children Under Five
Children under the age of five are susceptible to stunting, a chronic form of malnutrition. Chronic undernutrition and restricted access to wholesome food and medical care are the causes. According to the height-for-age index, children with stunted growth are usually shorter than average for their age. Stunting can cause major cognitive problems, such as slower motor development, diminished brain function, and subpar academic performance, in addition to physical growth delays.
Wasting in Children Under Five
Wasting is another critical form of malnutrition in young children. It happens when a child becomes dangerously underweight for their height due to sudden food shortages or illness. This condition, also called acute malnutrition, develops quickly and is diagnosed using the weight-for-height index or by measuring the mid-upper arm circumference (MUAC). Wasting can be either moderate or severe and significantly increases the risk of early death if not treated promptly.
Protein-Energy Malnutrition (PEM)
Protein-energy malnutrition, or PEM, occurs when the body doesn’t get enough calories or protein to function properly. While food insecurity is a leading cause, PEM is also common among patients with chronic illnesses like cancer or kidney failure undergoing dialysis. PEM appears in two main forms: marasmus, marked by severe weight loss, and kwashiorkor, which causes fluid retention (edema) and fatty liver. Both conditions are life-threatening and require immediate medical attention.
Micronutrient Deficiency
Micronutrient deficiency is a hidden form of malnutrition that arises when the body lacks vital vitamins and minerals. This can happen due to a poor diet or because the body isn’t absorbing nutrients effectively. Common deficiencies include iron, zinc, iodine, vitamin D, vitamin A, and vitamin C. These shortages can weaken the immune system, cause fatigue, and lead to muscle weakness. Preventing micronutrient deficiency involves eating a varied diet rich in fruits, vegetables, lean proteins, and whole grains.
Overnutrition
While often overlooked, overnutrition is also a type of malnutrition. It happens when a person consumes too many calories, fats, or sugars. Overnutrition is linked to several health risks, including obesity, heart disease, type 2 diabetes, stroke, and some types of cancer. Maintaining a healthy weight through balanced eating and guidance from a dietitian can help manage and prevent these conditions.
Secondary Malnutrition
Secondary malnutrition occurs when the body can’t absorb or utilize nutrients properly due to an underlying medical condition. Diseases affecting the gastrointestinal system, liver, or infections can all interfere with nutrient absorption. This form of malnutrition can exist even when someone is eating a balanced diet. It often presents with symptoms like nausea, vomiting, or reduced appetite and requires addressing the underlying health issue to restore proper nutrition.
Malnutrition Symptoms
Depending on the kind and severity of the nutritional deficit, malnutrition can cause a range of symptoms that affect various body parts. Malnutrition can have an impact on your energy levels, appearance, and general health in addition to making you underweight. Key indicators of malnutrition include the following:
Feeling constantly tired or unusually weak
Difficulty breathing or shortness of breath
Episodes of lightheadedness or dizziness
Reduced muscle strength or muscle wasting
Noticeable hair thinning or hair loss
Nails becoming weak, brittle, or breaking easily
Cuts and wounds taking longer to heal than usual
Losing weight without trying or an unexplained drop in weight
Getting sick more often due to frequent infections
Swelling in the abdomen or lower limbs
If you notice one or more of these symptoms, it may be a sign of malnutrition. Identifying the issue early can help prevent more serious health complications. Speak with a healthcare provider to evaluate your nutritional status and create a plan to improve it.
Why Does It Happen?
Malnutrition happens when the body doesn’t get the right mix of nutrients it needs to stay healthy and work properly. There are several key reasons why someone may develop malnutrition, including the following:
Age factors: Young children under five and older adults are especially vulnerable.
Chronic health issues: Conditions such as celiac disease, Crohn’s disease, or long-term infections can interfere with nutrient absorption.
Poverty: Limited financial resources often make it difficult to buy nutritious and affordable food regularly.
Food insecurity: Living in areas with little access to fresh and varied food—often known as food deserts—can lead to poor dietary intake.
Limited healthcare: Inadequate access to medical support means nutritional issues and underlying health problems may go untreated.
Unbalanced diet: Eating meals that are low in essential nutrients can prevent the body from performing basic functions effectively.
Restrictive eating habits: Cutting out entire food groups or following overly strict diets can lead to nutrient deficiencies.
The Diagnostic Process
Healthcare providers first assess your daily diet and talk about your medical history in order to diagnose malnutrition. In order to determine whether you are malnourished or to find any other potential health problems, they also perform particular tests and search for outward indicators that might point to a deficiency of nutrients.
Some commonly used tests for diagnosing malnutrition include:
Blood tests – These help detect anemia and check for vitamin and mineral deficiencies.
Body Mass Index (BMI) – This test calculates your height-to-weight ratio, which helps determine if you’re underweight or at risk.
Mid-upper arm circumference (MUAC) – This measures the size of your upper arm and can help assess nutritional status, especially in children and older adults.
Skinfold thickness test – By measuring the thickness of skin folds, doctors can estimate body fat levels and overall nutritional health.
Serum albumin test – This blood test evaluates the levels of albumin (a key protein) to check for protein deficiencies, which are often linked to malnutrition.
CT or MRI scans – These imaging techniques provide detailed internal views of organs and can help detect digestive issues that may be causing malnutrition.
A nutrition-focused physical exam (NFPE) is frequently performed by a registered dietitian to determine the severity of malnutrition. This thorough examination looks for symptoms that could indicate nutritional deficiencies, such as decreased physical strength, brittle nails, thinning hair, muscle loss, and thinning fat layers beneath the skin.

Malnutrition Treatment
Restoring and maintaining a healthy nutritional balance in the body is the main goal of treating malnutrition. For the body to perform at its peak, this entails making sure that all necessary nutrients—such as vitamins, minerals, proteins, and calories—are continuously provided. Correcting nutritional deficiencies and determining and treating any underlying causes of the condition are the main goals of treatment.
Making dietary changes is one of the most crucial actions in combating malnutrition. This could entail consuming more foods high in nutrients or increasing caloric intake through thoughtfully prepared, well-balanced meals. In more severe situations, medical practitioners might suggest specially prepared meals or dietary supplements to aid in healing and promote wellness.
When malnutrition is linked to an underlying medical issue, it’s critical to treat that condition alongside dietary changes. For instance, in cases where digestive disorders like Crohn’s disease hinder nutrient absorption, appropriate medication can help the body better absorb and utilize nutrients, making the overall treatment more effective.
How To Prevent Malnutrition
Malnutrition can be avoided by acting quickly to address your dietary needs and treat any underlying medical conditions. Here are some doable and efficient ways to lower your risk of malnutrition:
Recognize how drugs affect your appetite:
Certain drugs can make you less hungry, which makes it more difficult to eat enough. If your appetite changes, talk to your doctor about how to continue eating healthily while undergoing treatment.
Eat a well-rounded diet:
Focus on a diet rich in essential nutrients. Include plenty of fruits, vegetables, whole grains, dairy, and lean proteins. Prioritize foods that are good sources of potassium, calcium, vitamin D, and vitamin B12. Fortified food options can also fill nutritional gaps and help protect against malnutrition.
Seek advice from a nutrition professional:
Working with a registered dietitian can provide you with a customized meal plan that supports your health goals and prevents malnutrition. They can help ensure you’re getting the right balance of nutrients based on your personal needs.
Keep moving and stay active:
Regular physical activity, even something you simply enjoy like walking or light exercise, can help maintain or build muscle mass. Staying active supports your overall health and plays a key role in reducing the risk of malnutrition.
Complications
Malnutrition, when left untreated, can cause a range of severe health problems. Common symptoms and complications include:
Irregular heartbeat
Fainting spells
Chest discomfort
Constipation or diarrhea
Stomach pain
Trouble breathing
Muscle loss (sarcopenia)
Weak bones (osteopenia)
