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

For individuals with Hereditary Hemorrhagic Telangiectasia (HHT), regular, low-to-moderate intensity exercise is generally recommended and beneficial for maintaining cardiovascular health and overall well-being. However, because HHT can involve fragile blood vessels and potential organ involvement, it is essential to obtain medical clearance and avoid high-impact activities or maneuvers that cause significant spikes in blood pressure.

Is exercise safe for those living with Hereditary Hemorrhagic Telangiectasia?

Living with Hereditary Hemorrhagic Telangiectasia often leads to a sedentary lifestyle out of fear of triggering a bleed. However, clinical consensus suggests that moderate movement helps manage the chronic fatigue often associated with HHT-related anemia. While exercise is generally safe, the "safe" threshold depends entirely on your specific pattern of organ involvement, such as pulmonary arteriovenous malformations (PAVMs) or hepatic involvement. Always consult your HHT specialist before beginning a new routine to ensure your heart and lungs can handle the increased workload.

What types of exercise are recommended for Hereditary Hemorrhagic Telangiectasia patients?

The goal is to improve fitness without placing excessive strain on the vascular system. Focus on aerobic and resistance activities that allow for steady, controlled breathing. Recommended activities include:

• Walking and light hiking: Excellent for cardiovascular conditioning at your own pace.


• Swimming: Provides a full-body workout with minimal joint impact and a cool environment, which can be helpful for those who experience flushing.


• Yoga and Pilates: Focus on flexibility and core strength, provided you avoid inverted poses (like headstands) that increase intracranial or cephalic blood pressure.


• Light resistance training: Using low weights or resistance bands to maintain muscle mass without the extreme straining associated with heavy powerlifting.

Which activities should be avoided when managing Hereditary Hemorrhagic Telangiectasia?

Patients should approach activities that cause rapid, extreme increases in blood pressure with significant caution. Avoid the "Valsalva maneuver" (straining while holding your breath), which is common in heavy weightlifting, as this can increase pressure on fragile telangiectasias. Additionally, high-contact sports (e.g., boxing, rugby, or martial arts) are generally discouraged due to the high risk of trauma and uncontrolled bleeding. If you have been diagnosed with pulmonary arteriovenous malformations, your physician may advise against high-altitude activities or scuba diving due to oxygen saturation concerns.

How can I safely start an exercise program?

The key to success with Hereditary Hemorrhagic Telangiectasia is the "start low, go slow" approach. Begin with 10–15 minutes of light activity, three days a week, and monitor how your body responds. If you experience unusual nosebleeds, shortness of breath, or dizziness, stop immediately and contact your healthcare team. Physical therapy can be a vital bridge, as a trained therapist can design a specialized program that accounts for your unique vascular profile and energy levels. On days when fatigue is high, utilize "pacing"—break your exercise into shorter, 5-minute segments throughout the day rather than one continuous session.
