Health Risks Associated with Being Overweight

Being overweight or obese is not only about look — it’s a serious health concern that can lead to chronic diseases and decreased quality of life. When the body carries excess fat, it can interfere with main processes like metabolism, hormone regulation, and cardiovascular function.

Health RiskDescription
Heart Disease & StrokeExcess body fat raises cholesterol and blood pressure, increasing the risk of heart attack and stroke — two of the leading causes of death globally.
Type 2 DiabetesBeing overweight can lead to insulin resistance, which disrupts blood sugar regulation and increases the risk of developing Type 2 diabetes.
High Blood PressureExtra fat tissue demands more oxygen and nutrients, forcing the heart to work harder and raise blood pressure, which strains the cardiovascular system.
Sleep ApneaExcess weight, particularly around the neck, can narrow airways and cause breathing interruptions during sleep, leading to fatigue and reduced sleep quality.
Joint ProblemsCarrying extra weight increases pressure on joints, especially knees and hips — leading to pain, inflammation, and conditions like osteoarthritis.

Maintaining a BMI within a healthy range can significantly reduce these risks and promote long-term health.

Health Risks Associated with Being Underweight

Being underweight can be just as worrying as being overweight. When your body lacks enough fat and muscle mass, it can impact energy levels, immune system, and even organ function.

Health RiskDescription
Nutrient DeficienciesUnderweight individuals often fail to get enough essential nutrients including vitamins A, D, E, and K which are critical for strong bones, healthy skin, and a well-functioning immune system.
Bone WeaknessA low BMI is linked to reduced bone mineral density, increasing the risk of osteoporosis and bone fractures.
Hormonal ImbalancesBeing underweight can disrupt hormone production. In women, it can cause irregular menstrual cycles or fertility issues; in men, it can lower testosterone levels.
Weak Immune SystemInsufficient nutrition can weaken immune defenses, making the body more vulnerable to infections and slowing recovery.
Low Energy and FatigueWithout adequate calorie intake, the body lacks the energy it needs, leading to persistent tiredness, poor focus, and decreased physical performance.

Maintaining a balanced diet and a healthy BMI supports your immune function, bone strength, and overall vitality.
