Abdominal Muscle Spasms When Bending Over: Causes & Relief

Abdominal muscle spasms on forward flexion can arise from:

Common Causes

• Muscle strain – weak core, sudden movement, overuse.
• Nerve irritation – thoracic/lumbar radiculopathy, intercostal neuralgia.
• Dehydration/electrolyte imbalance – low K⁺, Mg²⁺, Ca²⁺.
• Visceral referral – gallbladder, pancreatic, colonic pathology.
• Abdominal wall hernia – triggered by increased intra-abdominal pressure.
• Post-surgical adhesions or nerve entrapment.

Self-Management

• Hydration + electrolyte-rich foods.
• Core strengthening (planks, bird-dog, dead bug – progressive).
• Dynamic warm-up before activity; avoid sudden flexion.
• Heat for chronic tightness; ice for acute strain.
• OTC NSAIDs if no contraindications.

Red Flags

• Severe, unremitting pain
• Radiating to chest/back (cardiac/vascular)
• Fever, vomiting, hematemesis/melena
• Neurologic deficits

Seek evaluation if persistent, worsening, or red flags present.
