Generally speaking, probiotics such as Bacillus acidophilus, Bifidobacterium bifidum, Lactobacillus acidophilus and Bacillus casei can be taken orally to relieve diarrhoea symptoms by regulating intestinal flora imbalance; intestinal calcium channel blockers such as pivetonium bromide can also be chosen to relieve diarrhoea symptoms by regulating intestinal functions; adsorbent anti-diarrhoea drugs such as Simethicone and medicinal charcoal can also be used; if diarrhoea is severe, loperamide or compound difenoxil can be chosen for anti-diarrhoea treatment, but should not be used for a long time.
