The short explanation
Yes, for many people with knee osteoarthritis, losing even a modest amount of weight can reduce pain and improve how well they can move. Each step puts several times your body weight through the knees, so reducing weight lowers the load on the joint noticeably. Weight loss works best combined with regular exercise, especially strengthening the thigh muscles. A physiotherapist can suggest knee-friendly exercises such as cycling, water exercises and specific strengthening moves. Together, these are among the most effective treatments for knee osteoarthritis.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Gradual weight loss through changes in diet and activity is more likely to last than crash diets. A dietitian can help plan Indian meals that suit you.
- If knee pain makes walking hard, exercises done sitting or in water can help you stay active.
- Other conditions such as diabetes, thyroid problems or medicines can affect weight, and are worth discussing with your doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
