Did you know that 70% of your immune system is in your gut?

Your gut doesn't just digest: it also protects your immune system.

When we think about the immune system, we often imagine defenses, vitamins, or frequent colds. However, Few people know that a very important part of our immune response is located in the gut. This means that your digestive health not only influences how you process food, but also how your body responds to viruses, bacteria, inflammation, and internal imbalances.

The gut is one of the body's main lines of defense . Every day it comes into contact with food, toxins, microorganisms, medications, stress, and lifestyle habits. Therefore, when the gut is irritated, inflamed, or out of balance , the body can become more vulnerable.

What is the relationship between the gut, microbiota, and the immune system?

The gut is home to the gut microbiota, a collection of bacteria, fungi, and other microorganisms that play essential roles in health. A balanced microbiota helps maintain good digestion, promotes nutrient absorption, and contributes to regulating the immune response.

When this microbiota is altered, what many people describe as " low defenses" can appear : frequent tiredness, heavy digestion, gas, abdominal bloating, food intolerances, reactive skin, repeated colds or a feeling of not fully recovering.

That's why gut health isn't a fad. It's a fundamental part of a holistic approach to health.

Inflammation: a sign you shouldn't ignore

Inflammation is a natural response of the body to protect itself. The problem arises when this inflammation persists for a long time. In these cases, the body can enter a state of constant alert , consuming energy and weakening its ability to repair itself.

Many people live with symptoms they consider "normal" : Bloating after eating, constipation, diarrhea, heartburn, fatigue, headaches, brain fog, or skin changes. However, these signs can indicate that your gut needs attention.

At Dr. Janeth Vitality , the goal is to look beyond the symptom and understand what may be happening in the body from a medical, nutritional, and holistic perspective.

Why do you get sick so often?

If you get sick easily, have trouble recovering, or feel your energy is low, it's important to look at your entire lifestyle : diet, rest, stress, digestion, inflammation, daily habits, and possible nutritional deficiencies.

The immune system doesn't work in isolation. It's connected to the gut, the nervous system, hormones, and metabolism. That's why a truly personalized approach can help you identify which factors are affecting your vitality.
