psyllium

Psyllium is a dietary fiber used to relieve occasional constipation and to maintain regularity of bowel movements.

Psyllium is a bulk-producing laxative that is available over-the-counter (OTC) as capsules or powders and is derived from the seed husks of the herb Plantago ovata. Psyllium husks are composed of insoluble fiber that cannot be digested. The psyllium husks absorb water and expand to many times their original size, increasing stool quantity and making stools softer and easier to eliminate.

Psyllium is also used as an antidiarrheal because it absorbs the excess water in the colon and adds bulk to the stools. It is popularly taken for weight management because it expands in the stomach and produces a feeling of fullness, resulting in reduced calorie consumption. In addition, studies indicate it may help in lowering unhealthy LDL cholesterol levels by absorbing bile acids and cholesterol in the intestines which are then eliminated in the stools.

Psyllium uses include the following:

• Constipation
• Diarrhea
• Fecal incontinence
• Hemorrhoids
• Ulcerative colitis
• Hyperlipidemia, a condition of high levels of blood fats (lipids)

• Do not take psyllium in the following conditions:
  • Hypersensitivity to psyllium
  • Gastrointestinal (GI) obstruction
  • GI ulceration
  • Swallowing difficulties (dysphagia)
  • Fecal impaction
  • Symptoms of appendicitis or other conditions that require immediate surgical intervention (acute surgical abdomen)
  • Rectal bleeding
• Use psyllium with caution in elderly patients. Elders may have insufficient fluid intake which may predispose them to fecal impaction and bowel obstruction.
• Some products may contain phenylalanine, an amino acid; avoid these products if you have phenylketonuria, a condition that causes excess phenylalanine buildup.

Common side effects of psyllium include:

• Constipation
• Abdominal cramps
• Diarrhea
• Esophageal obstruction
• Intestinal obstruction
• Allergic reaction in people sensitive to inhaled or ingested psyllium
