Cannot Live Without Laxatives? The Laxative Dependence Ruining Your Gut

When suffering from constipation, the first thing many people reach for is likely a laxative. However, did you know that chronic use of laxatives can bring about severe dependence and inertia in our gut? This is not simply a habitual issue, but a medical condition where the function of the gut itself can change and become damaged. In particular, stimulant laxatives act by directly irritating the intestinal wall to promote the secretion of water and electrolytes, forcibly inducing intestinal peristalsis. Initially, the effect is fast and powerful, making it easy to think that laxatives are the best solution. But here lies the problem: the gut gradually forgets how to move on its own without powerful external stimulation. Our gut contains an elaborate neural network called the enteric nervous system that operates independently of the brain, and the long-term use of stimulant laxatives can damage the neurons of this enteric nervous system or blunt their function. Ultimately, the nerves of the intestinal wall become desensitized and the smooth muscle responsible for peristalsis weakens, resulting in tolerance where the gut barely responds even when the drug dosage is increased. This is also called colonic inertia or lazy bowel syndrome. The gut loses the strength to push stool out on its own. Furthermore, the misuse and abuse of laxatives severely impacts the microbial environment in the gut, namely the gut microbiome. As the balance of beneficial bacteria is disrupted, gut health deteriorates further, which can lead to decreased immunity, indigestion, and even mood changes. When the gut becomes dependent on medication, one falls into a vicious cycle of suffering from even more severe constipation without the drug. This situation goes beyond simple constipation and can escalate into a serious condition affecting whole-body health, so it must never be taken lightly. To help our gut regain its original vitality, our efforts to care for the gut through everyday wisdom rather than drugs are truly important from now on.
