Long-term use of antibiotics may trigger irritable bowel syndrome, as these drugs limit the growth of "friendly" intestinal bacteria. To replenish these bacteria in your intestine, take supplements of acidophilus bacteria. To ease many irritable bowel symptoms, increase the fibre in your diet. Legumes, whole grains, fruits and vegetables are good sources of fibre, as are psyllium and oat bran supplements. Drink lots of water to lubricate the digestive system and choose foods high in essential fatty acids such as flaxseed and fish.
