Dysbiosis occurs when the balance between beneficial and opportunistic bacteria is broken. The most common causes in the modern world are:
- Western diet: High in refined sugars, saturated fats, and ultra-processed foods, but poor in fiber.
- Excess hygiene and disinfectants: We live in "too clean" environments that deprive us of exposure to natural microbes.
- Recurrent medications: Not only antibiotics, but also the chronic use of anti-inflammatories (NSAIDs) or stomach protectors.
- Environmental toxins: Pesticides, food additives, and pollution.
- Lack of rest: Sleep disruption alters microbial composition almost immediately.
