Both being significantly overweight and underweight can have adverse effects on health. Which is "worse" for your health depends on various factors, including the degree of excess weight or underweight, individual genetics, and specific health conditions. Here's a brief overview of the potential health risks associated with both:

Health Risks of Being Overweight:

1. Cardiovascular Problems: Excess weight, particularly abdominal fat, can increase the risk of heart disease, hypertension (high blood pressure), and stroke.

2. Type 2 Diabetes: Being overweight is a major risk factor for developing type 2 diabetes, as it can lead to insulin resistance.

3. Joint Issues: Carrying excess weight puts more stress on joints, which can lead to conditions like osteoarthritis.

4. Respiratory Problems: Obesity can contribute to sleep apnea and other respiratory issues.

5. Cancer Risk: Some types of cancer, such as breast, colon, and prostate cancer, are more common among overweight individuals.

6. Metabolic Syndrome: This cluster of conditions, including high blood pressure, high blood sugar, high cholesterol levels, and excess abdominal fat, is more prevalent in overweight individuals and increases the risk of heart disease and type 2 diabetes.

Health Risks of Being Underweight:

1. Nutritional Deficiencies: Underweight individuals may not be getting enough essential nutrients, leading to deficiencies in vitamins and minerals, which can weaken the immune system and overall health.

2. Muscle and Bone Weakness: Insufficient body weight can lead to muscle wasting and decreased bone density, increasing the risk of fractures.

3. Hormonal Imbalances: Underweight individuals may experience hormonal imbalances, such as disruptions in menstruation in women, which can affect fertility.

4. Weakened Immune System: A lack of proper nutrition can compromise the immune system, making underweight individuals more susceptible to infections.

5. Organ Damage: Severe underweight conditions can lead to organ damage, particularly to the heart, liver, and kidneys.

6. Mental Health Issues: Being significantly underweight can be associated with mental health concerns, such as depression, anxiety, and eating disorders.

In summary, both being significantly overweight and underweight can have serious health consequences. It's essential to maintain a balanced and healthy weight for your individual body type and to focus on overall well-being, including proper nutrition, regular physical activity, and mental health. If you have concerns about your weight or its impact on your health, it's advisable to consult with a healthcare professional who can provide personalized guidance and support.
