Constipation: Causes, Diagnosis, Treatment, and Prevention with Dr. Carmen Fong

Understanding Constipation

• 🎯 Constipation is defined by symptoms like difficulty pooping, hard stools, straining, or feeling of incomplete evacuation, with a recommended maximum of 2-5 minutes on the toilet.
• 💡 It can be categorized into six types: opioid-induced, fiber/exercise-induced, drug/medication-induced, bacterial-induced (like C. diff), and functional constipation disorders.
• 📊 The most common cause is functional constipation, where the issue stems from anatomy and physiology rather than other underlying problems.

Causes and Initial Management

• 💧 Insufficient fiber and water intake are primary culprits, as fiber without adequate water can lead to a hardened stool.
• 🏃 Lack of physical movement also slows down gastrointestinal motility.
• ✅ The initial conservative management involves increasing soluble and insoluble fiber (25-35g/day), drinking 2-3 liters of water daily, regular exercise (30 mins, 3x/week), taking probiotics for frequency, and magnesium oxide for frequency and consistency.
• 🥝 Eating two kiwi fruits daily is a proven method to improve bowel movements.

Medical Evaluation and Advanced Tests

• 🩺 A physical exam includes palpating the abdomen and a digital rectal exam (DARE), which now includes anoscopy to inspect the anus and examine pelvic floor and sphincter muscles.
• 🔬 For persistent cases, tests like MRI defography (to assess pelvic floor function during a bowel movement) and Sitzmark studies (swallowing capsules with markers to track transit time) are used to diagnose gut dysmotility or pelvic floor dysfunction.
• ⚡ Anal manometry tests sphincter muscle function to identify issues with relaxation.

Treatment for Refractory Cases

• 💊 If conservative measures fail, stronger medications may be prescribed for gut issues, while pelvic floor physical therapy is recommended for butt (outlet obstruction) issues.
• 💉 Botox injections can be used to relax overactive or spasming sphincter muscles, addressing issues caused by over-exercising pelvic floor muscles or behavioral patterns.
• 🏥 In severe cases, such as fecal impaction from opioid use post-surgery, treatment may involve oral laxatives, enemas, suppositories, or in rare, extreme cases, manual disimpaction or surgery like a colectomy.

Red Flags and Prevention

• 🚨 Red flags for constipation include bleeding (even bright red blood should be checked), unintentional weight loss, persistent abdominal bloating, black or pencil-thin stools, and a family history of IBD or colorectal cancer.
• 🩺 Prompt medical attention is advised for any significant change in bowel habits.
• 📚 Prevention is key, emphasizing consistent intake of fiber, water, and exercise, and addressing issues early by consulting a doctor when experiencing concerning symptoms.
