Metabolic syndrome

It is not a disease. It is a group of five risk factors that show up together and dramatically raise your odds of heart disease, stroke and type 2 diabetes.

Diagnosis

You have metabolic syndrome if you have at least three of these five:

  1. A large waistline — abdominal obesity.

    • Men: 102 cm or more.
    • Women: 88 cm or more.

    This fat around the organs is the main driver. It is metabolically active, and it disturbs the hormones.

  2. High blood pressure: 130/85 mmHg or more, or on blood-pressure medicines. Consistently raised pressure strains the arteries and the heart.

  3. High fasting blood sugar: 100 mg/dL or more, or on glucose-lowering medicines. An early sign of insulin resistance, even before diabetes develops.

  4. High triglycerides: 150 mg/dL or more, or on treatment. Triglycerides are a type of blood fat; high levels signal that your body isn’t handling fat well.

  5. Low HDL cholesterol — the “good” cholesterol.

    • Men: below 40 mg/dL.
    • Women: below 50 mg/dL.

    HDL helps clear the bad cholesterol. Low levels mean less protection.

Why it happens

The root cause is usually insulin resistance. Your cells stop responding well to insulin, so your pancreas pumps out more. That extra insulin, high blood sugar and fat storage become a vicious cycle.

The biggest contributors:

  • Excess weight, especially around the belly.
  • A sedentary lifestyle: muscle is key for storing blood sugar.
  • Diet: high in refined carbohydrates, sugar and ultra-processed food.
  • Genetics and age: the risk goes up after 40, and family history matters.
  • Others: poor sleep, chronic stress, smoking, and conditions like PCOS.

What it means

Metabolic syndrome means twice the risk of heart disease and stroke, and five times the risk of type 2 diabetes. It is also linked to fatty liver disease, kidney disease and some cancers. The frightening part: you can have it for years with no symptoms at all.

Turning it around

The good news: it is largely reversible through lifestyle. Medicines help, but habits do the heavy lifting.

  1. Move more, sit less.
    • 150 minutes a day of walking, cycling or swimming.
    • Add strength training twice a week. Muscle mass improves insulin sensitivity fast.
    • Even 10-minute walks after meals blunt the spikes in blood sugar.
  2. Rethink your plate.
    • Prioritise fibre, protein and healthy fats. Think Mediterranean style: vegetables, fish, olive oil, nuts, legumes, whole fruit.
    • Limit sugary drinks, refined grains and ultra-processed snacks. They spike insulin and triglycerides.
    • Aim to lose weight: losing just 5–10% of your body weight can reverse most of the markers.
  3. Sleep and stress.
    • 7–9 hours of sleep. Poor sleep worsens insulin resistance overnight.
    • Chronic stress raises cortisol, which increases belly fat and blood sugar. Walking, breathing exercises or hobbies help.
  4. Quit smoking and limit alcohol. Both directly worsen blood pressure, triglycerides and insulin resistance.
  5. Medicines when needed. Your doctor may prescribe medicines for blood pressure, cholesterol or blood sugar. They manage the numbers while you work on the root causes.

Conclusion

It is a wake-up call — your body saying “the current system isn’t sustainable”. The criteria are all measurable, which means you can track your progress.

Health is priceless. Unfortunately, most of us only realise it when we lose it. Most of the time, it is in our own hands. If you lead a principled life — walking, controlling your diet, practising yoga and meditation — life is going to be very, very comfortable, and it will keep the doctor miles away.
