Is it advisable to do exercise when affected by Dent Disease? Which activities would you suggest and how intense should they be?

Yes, regular, moderate physical activity is generally recommended for individuals with Dent Disease to help maintain bone density and overall cardiovascular health. Because Dent Disease affects kidney function and bone mineral metabolism, exercise programs must be tailored to your specific renal status and should always be cleared by your nephrologist.

Is exercise safe for those living with Dent Disease?

For patients with Dent Disease, movement is vital for mitigating the risk of nephrocalcinosis and osteomalacia. While there is no "one-size-fits-all" protocol, light-to-moderate exercise helps preserve muscle mass and supports bone strength. It is essential to avoid high-intensity activities that lead to extreme dehydration, as fluid balance is critical for managing Dent Disease symptoms.

What types of exercise are recommended?

Focus on low-impact, sustainable activities that do not place excessive stress on the kidneys or joints. Beneficial activities include:

• Walking or light hiking: Excellent for cardiovascular health and bone loading.


• Swimming or water aerobics: Provides resistance without impact, which is ideal if you experience bone pain.


• Yoga or Pilates: Enhances core strength and flexibility while allowing for easy modification on lower-energy days.


• Light resistance training: Using bands or light weights can help maintain bone density, a common concern in Dent Disease.

How can I start an exercise program safely?

Begin by consulting your nephrologist to establish your current electrolyte levels and renal function. Start with 10-15 minutes of low-intensity movement, increasing duration by no more than 10% per week. Always prioritize hydration and monitor your urine output. If you experience persistent bone pain or dizziness, stop immediately and discuss these symptoms with your care team, as they may indicate a flare of Dent Disease complications.

The role of physical therapy and pacing

A physical therapist can help you design a routine that accommodates the specific musculoskeletal challenges of Dent Disease. On days when fatigue is high, utilize "pacing": break your exercise into two 10-minute sessions rather than one 20-minute session. Listening to your body is not a sign of weakness; it is a clinical necessity for managing this rare condition.
