Thumb Arthritis

Thumb Arthritis

Diagnosis Explanation:

Thumb arthritis (also called carpometacarpal (CMC) arthritis) is a degeneration of the cartilage in the base of the thumb, where the metacarpal bone meets the wrist. It commonly develops due to aging, repetitive hand use, or previous injuries and can significantly affect grip strength and daily activities.

Symptoms:

  • Pain, swelling, and stiffness at the base of the thumb.
  • Weak grip strength, making pinching and grasping objects difficult.
  • Clicking or grinding sensation with thumb movement.
  • Thumb deformity (in advanced cases).

Specific Work Modifications:

  • If your job involves typing or writing: Use an ergonomic keyboard, voice dictation software, and padded pens.
  • If your job requires manual labor: Avoid forceful pinching, gripping, or repetitive hand movements. Use wrist/thumb braces when necessary.
  • If your job is desk-based: Keep hands supported, take frequent breaks, and use adaptive equipment.
  • Avoid: Prolonged gripping, repetitive thumb use, and forceful pushing motions.

Specific Activity Modifications:

  • If you play an instrument or craft: Use larger-handled tools and finger splints for support.
  • If you play sports: Avoid racket sports, golf, and activities requiring strong thumb grip.
  • If you garden or cook: Use ergonomic tools with padded handles.
  • Avoid: Prolonged pinching, twisting motions, and forceful thumb use.

Recommended Supplements:

  • Collagen Peptides – 10g daily for cartilage repair.
  • Glucosamine & Chondroitin – 1500mg/1200mg daily for joint lubrication.
  • Omega-3 Fatty Acids – 1000mg daily to reduce inflammation.
  • Vitamin D3 + Calcium – 1000 IU/500mg daily for bone health.
  • Turmeric (Curcumin) – 500-1000mg daily for natural pain relief.

Recommended Nutrition and Hydration:

  • Increase Lean Protein (chicken, fish, tofu, eggs) to support cartilage and tendon health.
  • Eat Anti-Inflammatory Foods (berries, leafy greens, turmeric, nuts) to reduce joint pain.
  • Consume Hydrating Foods (cucumber, watermelon, citrus) to maintain tissue flexibility.
  • Limit Processed Foods & Sugars to prevent inflammation.
  • Hydration: Drink 8-10 cups of water daily to support joint lubrication.
