Metabolic syndrome in childrenits hidden causes treatment methods and early prevention

In recent years, there has been a noticeable increase in obesity rates among children, which raises significant concerns due to the serious health complications it can cause. One of these complications is metabolic syndrome, a medical condition that includes a group of disorders related to excess weight such as high blood pressure, elevated blood sugar levels, and abnormal cholesterol levels.

Although this syndrome is often diagnosed in adults, its appearance in childhood has become increasingly common due to unhealthy lifestyle habits.

In my Medical Guide, find out: What is metabolic syndrome in children? What are its main causes and symptoms? And how can it be prevented and treated early before it impacts the child’s future health?

What is Metabolic Syndrome in Children?

Metabolic syndrome is a group of health problems that can affect children, especially those over 10 years old. These problems increase their risk of developing serious diseases like heart disease and diabetes later in life.

The issues that make up this syndrome include:

Excess fat around the belly: This means the waist circumference is larger than normal, which is a sign of harmful fat accumulation.
High blood pressure: Blood pressure levels higher than the normal range.
High triglycerides: A type of fat in the blood that is elevated beyond normal levels.
Low HDL cholesterol (good cholesterol): The cholesterol that helps protect the heart is lower than normal.
High blood sugar levels: Elevated blood sugar even if the child does not have diabetes.

If a child has more than one of these problems together, they are at greater risk of developing heart disease or diabetes in the future.

Simple Causes of Metabolic Syndrome in Children

Metabolic syndrome in children results from a combination of factors that affect the child’s body and health, including:

Obesity and belly fat: Excess weight, especially fat around the abdomen, is the main cause. This fat affects the body's ability to use insulin properly, increasing the risk of the syndrome.
Insulin resistance: This means the child's body needs higher amounts of insulin to control blood sugar levels, which over time can cause high blood sugar, increased fat levels, and high blood pressure.
Lack of physical activity: Low movement and exercise make the body less able to regulate fat and sugar, raising the risk.
Unhealthy diet: Foods high in saturated fats and sugars, like soda and fast food, cause fat buildup and metabolic problems.
Genetic factors: If the child's family has a history of diabetes or heart disease, the likelihood of the child developing the syndrome increases.
Hormonal changes during adolescence: Significant hormone shifts during puberty affect how the body metabolizes fat and sugar.
Stress and psychological pressure: Ongoing stress can impact hormone secretion, causing weight gain and insulin resistance.
Lack of sleep: Insufficient or disrupted sleep affects appetite hormones and metabolism, increasing risk.
Premature birth or low birth weight: Children born early or with low weight are more prone to metabolic problems later.
Short or no breastfeeding period: Breastfeeding helps regulate metabolism and protect against obesity; a short or absent breastfeeding period negatively affects this.
Exposure to secondhand smoke: Cigarette smoke in the home affects the child’s health and increases the risk of metabolic disorders.
Deficiency of certain vitamins and minerals: Such as vitamin D and zinc, which play important roles in weight regulation and metabolism.
Excessive consumption of sugary and carbonated drinks: High liquid sugar intake affects insulin sensitivity and increases the risk of the syndrome.
Chronic family or environmental stress: A poor psychological environment influences the child’s eating and activity behaviors, raising the risk.
Lack of sun exposure: Limited sunlight causes vitamin D deficiency, which plays a key role in metabolism regulation.

Symptoms of Metabolic Syndrome in Children

The syndrome appears through several signs and symptoms that parents may notice, including:

Obesity, especially abdominal obesity
Fat accumulation around the waist is noticeable and is an important indicator of the syndrome.
High blood pressure
The child may have high blood pressure without obvious symptoms, so regular monitoring during medical checkups is necessary.
High blood sugar levels
Often without clear symptoms, but tests show elevated sugar or poor insulin response.
High triglycerides (bad fats)
Increased levels raise the risk of heart and artery problems.
Low HDL cholesterol (good cholesterol)
A decrease in protective cholesterol increases the risk of heart disease.
Fatigue and sluggishness
The child may feel tired and less active even without illness.
Snoring and rapid breathing during sleep
Especially in children with breathing issues during sleep, such as sleep apnea.
Signs of insulin resistance on the skin
Dark, velvety patches may appear on the neck, underarms, or thighs — called Acanthosis nigricans.

Symptoms of Metabolic Syndrome in Infants

Infants usually don’t show clear symptoms but may exhibit:

Abnormal weight gain, especially around the abdomen.
Changes in eating or sleeping patterns.
In rare cases, tests may reveal insulin resistance or high blood lipids.

Stages of Metabolic Syndrome in Children and Infants

Stage One: Early weight gain and obesity
Fat starts accumulating mainly around the abdomen. Weight is higher than normal for age and height. Infants may show rapid weight gain.
Stage Two: Insulin resistance
Body cells respond less effectively to insulin, causing poor blood sugar control. Dark, velvety skin patches (Acanthosis nigricans) may appear. Infants may show changes in blood sugar or lipid tests.
Stage Three: Blood lipid disorders
High triglycerides and low HDL cholesterol increase the risk of cardiovascular disease.
Stage Four: High blood pressure
Blood pressure rises above normal levels, often without clear symptoms. Regular monitoring is important.
Stage Five: Appearance of associated health problems
Heart problems, increased risk of type 2 diabetes, and vascular issues may develop if untreated, leading to serious long-term complications.

How is Metabolic Syndrome Diagnosed in Children and Infants?

Diagnosis is based on:

Clinical examination:
Measuring weight, height, and waist circumference to detect central obesity.
Measuring blood pressure to check for hypertension.
Laboratory tests:
Fasting blood sugar after 8 hours of fasting.
Glucose tolerance test if needed.
Blood lipid profile to measure triglycerides and HDL cholesterol.
Insulin resistance tests by measuring insulin levels related to blood sugar.
Observation of skin signs:
Presence of Acanthosis nigricans is a strong indicator of insulin resistance.
Family and medical history:
Checking for family history of diabetes, heart disease, or hypertension.
Evaluating eating habits and physical activity level.

Diagnostic Criteria for Metabolic Syndrome in Children

Diagnosis requires at least 3 of the following:

Central obesity (large waist circumference).
High blood pressure.
Elevated fasting blood sugar or insulin resistance.
High triglycerides.
Low HDL cholesterol.

Health Problems That May Develop in Children with Metabolic Syndrome

Type 2 diabetes:
Insulin resistance and high blood sugar greatly increase risk.
Heart and vascular diseases:
High bad fats, low good cholesterol, and high blood pressure raise risks of atherosclerosis, heart attacks, and strokes.
High blood pressure:
Prolonged hypertension can damage the heart, kidneys, and nervous system.
Liver problems:
Fatty liver disease due to fat buildup, which may progress to liver fibrosis if untreated.
Sleep breathing problems:
Excess weight can cause sleep apnea, affecting sleep quality and overall health.
Joint and bone pain:
Extra weight stresses joints, causing pain and movement difficulty.
Psychological and behavioral issues:
Anxiety, depression, and concentration difficulties due to hormonal changes and psychological stress.
Polycystic ovary syndrome (PCOS) in girls:
Hormonal imbalances from the syndrome can lead to PCOS.
Weakened immunity:
Metabolic changes reduce immune function, increasing infection risk.
Respiratory issues:
Weight gain causes breathing difficulties and affects lung function.
Increased risk of some cancers:
Such as pancreatic and liver cancer due to chronic inflammation and obesity.
Growth problems:
Delayed growth or hormonal imbalances linked to insulin resistance.
Neurological problems:
Problems with memory, learning, and concentration due to metabolic effects on the brain.
Kidney disease:
High blood pressure and sugar damage kidney function over time.
Digestive issues:
Constipation, digestive disturbances, and irritable bowel syndrome linked to lifestyle and diet.
Eye problems:
High sugar and blood pressure can cause retinal damage even in children.
Vascular inflammation:
Fat and sugar accumulation cause chronic vessel inflammation.
Mental health deterioration:
Sleep disorders, mood swings, and low self-esteem related to weight and health issues.
Increased risk of thyroid disease:
Metabolic changes affect thyroid function.
Heart function deterioration:
Heart muscle enlargement or weakness due to chronic pressure.
Early coronary artery disease risk:
Can begin even in children with metabolic issues.

Treatment of Metabolic Syndrome in Children: Simple and Effective Steps

Metabolic syndrome is not just one disease; it’s a group of related health problems like high blood sugar, high fats, and high blood pressure. If left untreated, these can seriously affect your child’s health. Treatment should be comprehensive and focus on improving each part of the problem.

1. Lifestyle Modification: The Essential First Step

a. Healthy Diet

Reduce sugars, saturated fats, and salt in your child’s food.
Increase fruits, vegetables, whole grains, and healthy proteins such as fish, chicken, and lentils.
Divide meals into small, frequent portions to keep blood sugar steady.
Limit fast food, soda, and sugary juices.

b. Regular Physical Activity

Encourage your child to exercise for 60 minutes daily—walking, playing, swimming, or cycling.
Reduce screen time and promote active play.

c. Maintaining a Healthy Weight

Monitor your child’s weight and height regularly with a doctor.
If overweight, aim for gradual and healthy weight loss.

2. Medication: When Is It Necessary?

Medication is not the first choice but becomes important if lifestyle changes alone are not enough or if the condition is severe.

Blood Sugar Lowering Drugs

Metformin: helps the body use insulin better and lowers blood sugar.
Used especially if the child has insulin resistance or early type 2 diabetes.
Must be taken under close medical supervision.

Blood Pressure Medications

If high blood pressure persists, the doctor may prescribe:
- ACE inhibitors (e.g., Enalapril)
- Angiotensin receptor blockers (ARBs)
- Diuretics
The choice depends on the case and doctor’s guidance.

Cholesterol and Fat Lowering Medications

If cholesterol or triglycerides are very high, the doctor may prescribe:
- Statins to reduce bad cholesterol
- Vitamin B3 or other medicines to lower triglycerides
Use cautiously and with continuous medical monitoring.

3. Regular Medical Follow-Up: The Key to Successful Treatment

Regular check-ups with the doctor are very important to:

Monitor blood sugar to prevent diabetes progression.
Track blood pressure and adjust medications if needed.
Test blood fats and adapt treatment or diet accordingly.
Follow the child’s weight and growth, giving family advice on weight management.
Monitor liver and kidney functions to detect problems early.
Check mental and behavioral health because psychological support improves treatment adherence.

Psychological and Social Support for Children with Metabolic Syndrome: Important Steps for Parents

1. Regular Doctor Visits

Ideally, visit the specialist every 3 to 6 months depending on the child’s condition.
The doctor will set appropriate schedules for tests and follow-ups.

2. Necessary Medical Tests

Regular blood tests including:
- Fasting blood sugar
- Blood lipids (cholesterol and triglycerides)
- Liver and kidney function
Monitor symptoms and vital signs.
Report any new symptoms for timely medical intervention.

3. Adjusting Treatment Plan

The doctor may change diet plans or increase physical activity based on progress.
Medications may be started or adjusted under medical supervision.

4. Important Tips for Parents During Follow-Up

Keep track of appointments and don’t miss them.
Follow doctor’s instructions carefully on diet, activity, and medications.
Provide a supportive environment that promotes your child’s mental and physical health.
Don’t hesitate to ask the doctor any questions about your child’s health.

4. Psychological and Social Support Components

a. Family Support

Encourage your child to express feelings and thoughts without fear.
Provide continuous emotional support and genuine care.
Avoid criticism or teasing about weight or health condition.
Involve them in preparing healthy meals and exercising together.

b. School Support

Inform the school and teachers about your child’s condition for better support.
Ensure teachers handle the child kindly and protect from bullying.
Encourage participation in school sports and social activities.

c. Professional Psychological Support

If you notice anxiety, depression, or abnormal behaviors, consult a psychologist.
Psychological therapy helps the child manage stress and build confidence.
Cognitive behavioral therapy can improve self-esteem and promote healthy habits.

d. Social Support

Encourage making healthy friendships and participating in useful hobbies.
Reduce isolation and long screen time.
Join support groups or group activities to strengthen belonging.

5. Practical Advice for Parents on Treating Metabolic Syndrome in Children

Be a Healthy Role Model:
Show healthy eating and regular exercise yourself.
Listen Without Judgment:
Provide love, understanding, and support.
Involve the Child:
Let your child participate in choosing healthy foods and suitable physical activities.
Monitor Mental and Behavioral Health:
Seek professional help immediately if mood or behavior changes.

6. Surgical Treatment of Metabolic Syndrome in Children

When to Consider Surgery?

Surgery is rarely needed and is considered only if:

Severe obesity significantly harms health.
Serious related health issues exist such as:
- Severe high blood pressure
- Type 2 diabetes uncontrolled by medication
- Respiratory or heart diseases due to obesity
All attempts at lifestyle and medical treatment have failed over a long period.

Common Surgical Procedures for Children

Sleeve Gastrectomy:
Removes a large part of the stomach to reduce its size, helping reduce food intake and improve metabolic factors.
Gastric Bypass:
Alters the intestines to reduce nutrient absorption; rarely used in children due to complexity.

Important Notes on Surgery

The decision is made by a specialized medical team including pediatric surgeons, nutritionists, psychologists, and doctors.
Continuous close follow-up after surgery is essential to prevent complications.
Surgery is not a final solution alone and must be combined with lifestyle and dietary changes.
Surgery carries risks and is performed only in severe, unresponsive cases under strict medical supervision.
