Hyperbaric Oxygen Therapy for Radiation Proctitis: A Healing Path for Cancer Survivors in San Antonio

If you’re dealing with rectal bleeding, pain, urgency, or bowel changes after cancer treatment, especially radiation to the pelvis, you’re not alone.

Radiation proctitis can develop weeks, months, or even years after radiation therapy for cancers such as:

• Prostate
• Cervical
• Uterine
• Bladder
• Colorectal

​

While radiation successfully targets cancer, it can also injure surrounding soft tissue, especially the sensitive lining of the rectum and lower colon. This damage, often called radiation proctitis or soft tissue radiation injury, can disrupt your quality of life and leave you with symptoms that feel frustrating or even alarming.

At Hill Country Wound Care & Hyperbarics, we offer advanced, physician-led treatment with hyperbaric oxygen therapy (HBOT), a powerful solution that helps heal radiation-damaged tissue and provides real, lasting relief.

What Is Radiation Proctitis?

Radiation proctitis is inflammation and injury to the rectum caused by radiation therapy, particularly for cancers located in the pelvic region. While some patients develop symptoms shortly after completing radiation (acute proctitis), others may not experience issues until months or even decades later, a condition known as chronic radiation proctitis.

​

Common Symptoms of Chronic Radiation Proctitis:

• Rectal bleeding (often painless but persistent)
• Urgency or frequency of bowel movements
• Pain or burning during defecation
• Mucous discharge or loose stools
• Difficulty with normal rectal function

​

These symptoms can range from mild to severe, and when left untreated, can worsen over time.

Why Radiation Damages the Rectum

Radiation therapy is designed to kill cancer cells, but it can also damage small blood vessels and healthy tissues nearby. Over time, this results in:

​

• Reduced blood flow
• Tissue hypoxia (lack of oxygen)
• Scarring and fibrosis
• Poor healing capacity

​

When blood vessels shrink and scar over, they can’t deliver enough oxygen and nutrients to help the damaged tissue recover. This is why traditional treatments, such as creams, steroids, or dietary changes, often fail to resolve symptoms in the long term.

How Hyperbaric Oxygen Therapy (HBOT) Helps Radiation Proctitis Heal

Hyperbaric oxygen therapy works by delivering 100% pure oxygen inside a pressurized chamber, allowing your lungs to absorb dramatically more oxygen, up to 10 to 15 times more than normal air.

​

This oxygen-rich blood reaches even damaged, poorly perfused tissue, like the rectum and colon injured by radiation, and stimulates cell repair and new blood vessel growth.

​

Radiation proctitis isn’t just surface-level damage. It’s a wound deep inside your body that requires a unique, specialized approach. That’s exactly what HBOT provides. By delivering oxygen at a cellular level, hyperbaric therapy works from the inside out to restore damaged tissue, promote healing, and alleviate symptoms that other treatments may not fully resolve.

​

Proven Benefits of HBOT for Radiation Proctitis:

✅ Stimulates angiogenesis – New blood vessels form in areas of poor circulation

✅ Reduces inflammation and fibrosis – Less scarring, better long-term function

✅ Improves tissue oxygenation – Speeds healing in oxygen-starved areas

✅ Decreases rectal bleeding – Fewer disruptions, less anxiety

✅ Improves bowel function – Less urgency and discomfort

✅ Enhances immune response – Lowers risk of infection or chronic wounds

​

Studies show HBOT significantly improves symptoms in up to 85–90% of patients with chronic radiation proctitis, especially when treatment is started early.

What to Expect From HBOT at Hill Country

At Hill Country Wound Care & Hyperbarics, our San Antonio-based clinics provide HBOT in a calm, outpatient setting. Each session is overseen by a board-certified provider and administered by highly trained hyperbaric technicians.

Your Treatment Journey:

1. Consultation & Evaluation: We work closely with your referring gastroenterologist, oncologist, or primary care physician to confirm your diagnosis and build a tailored HBOT plan.

2. Treatment Sessions: You’ll typically receive 40 daily treatments, lasting about 90–120 minutes each. Sessions occur Monday through Thursday, with adjustments based on how your tissue responds.

3. Re-Evaluation: After 40 sessions, we reassess your symptoms and collaborate with your specialists to determine if additional sessions are needed.

4. Follow-Up Support: We provide guidance on post-treatment bowel health, symptom tracking, and coordination with your care team.
