Reversal of Lower-Extremity Intermittent Claudication and Rest Pain by Hydration

Area of Science:

• Vascular Medicine
• Peripheral Artery Disease
• Hydration Therapy

Background:

• Medical treatments for disabling intermittent claudication and critical limb-threatening ischemia often yield partial responses or fail.
• Peripheral vascular disease (PVD) significantly impacts quality of life, causing pain and limiting mobility.

Observation:

• A pilot study involved 36 patients with disabling intermittent claudication or rest pain due to PVD.
• Participants consumed over 2.5 liters of water daily for up to 6 weeks.
• Key metrics including ankle-brachial index, skin temperature, claudication time/distance, and pain intensity were monitored.

Findings:

• Increased water intake demonstrated significant improvements in ankle-brachial index (0.60 to 0.76) and foot skin temperature.
• Supervised treadmill exercise showed marked increases in claudication time (1.25 to 6.25 min) and distance (100 to 535 m).
• 35 out of 36 patients achieved the target daily water intake.

Implications:

• Adequate hydration (over 2.5 L/day) appears to be a potent, accessible intervention for PVD symptom management.
• This hydration strategy may offer a complementary or alternative approach to conventional PVD treatments.
• Further research is warranted to confirm these findings in larger, controlled trials.
