Can You Get Diarrhoea from Smoking? The Brutal Truth

Smoking is harmful. It’s certainly not the first time you’ve heard that. The nerve toxin nicotine is deposited at the so-called acetylcholine receptors, the receptors of the nervous system, which control important functions in your body. Among other things, nicotine stimulates the parasympathetic nervous system in your brain. 

This nervous system controls many of your internal organs, including the entire digestive system. Smoking leads to increased intestinal activity, an increase in gastric juice production and thus to stimulation of digestion, which is often associated with diarrhoea.

Constantly Diarrhoea from Smoking - This Is How it Happens

Smoking can hit your stomach. You probably know this unpleasant stomach upset when you smoke in the morning on an empty stomach. The inhalation of smoke causes harmful substances to enter your stomach via the mucous membranes of your mouth, throat and oesophagus. 

The nicotine irritates your stomach mucous membrane and thus promotes irritation and inflammation, which in turn can cause diarrhoea. This problem can also quickly lead to sleepless nights, which are characterised by dark circles around the eyes.

Smoking Causes Diarrhoea - Tobacco Smoking Damages the Stomach and Intestines

The nicotine that your body constantly absorbs acts as a messenger. This can influence various metabolic processes. Smoking not only affects your cardiovascular system and lungs but also your digestive system. There is nothing worse for your stomach and intestines than smoking.

Smoking triggers inflammatory processes in your body. If you smoke regularly, it can trigger chronic inflammatory bowel diseases such as ulcerative colitis or Crohn’s disease. Nicotine consumption increases your intestinal activity, which often leads to diarrhoea. Not only your intestines, but also your stomach is strongly attacked by tobacco consumption.

After Smoking Diarrhoea - Problems with Digestion

Smoking is often involved in the occurrence of diarrhoea. Smoking irritates your stomach, which you sometimes feel yourself. Especially the first cigarette in the morning often causes stomach and intestinal problems. You should always understand gastritis as a warning signal. 

Try to quit smoking or at least limit the amount of cigarettes you consume. At the same time you should change your eating habits. Your digestive system will thank you because problems with digestion can be quite stressful for you.
