"There is a constant communication between our brain and our stomach. Therefore, imbalances can cause changes in mood, increase the response to stress, anxiety and even depression," says cardiac surgeon Jeremy Londo, one of the most recognized in the United States.

In statements reported by Clarín, London states that “90% of serotonin is produced in our gastrointestinal tract.” This substance is related to mood, motivation and a feeling of calm.

It maintains that the gut is connected to the brain through a communication network known as the gut-brain axis. Therefore, what happens in the digestive system has a direct impact on the emotional. He emphasizes that "70% of our body's immune function lives in our intestine", hence the vital importance of maintaining a healthy digestive system, which helps us digest better and protect us from the action of viruses, bacteria and toxins.

The specialist emphasizes the importance of prevention in cardiovascular health. Through its website, podcast and social networks, it shares vital information to promote healthy lifestyles and the reduction of risk factors.

Healthy habits to avoid the operating room

London advises avoiding tobacco, reducing sugar and alcohol consumption, and adopting a balanced diet. These changes may prevent the need for surgical interventions.

Likewise, it recommends incorporating prebiotics and probiotics into the diet to strengthen intestinal health, as well as performing regular aerobic exercise to strengthen the heart and minimize the risk of cardiovascular diseases.

Imbalance in brain-stomach communication

The symptoms that indicate an imbalance in the communication between the brain and the stomach (gut-brain axis) are divided into digestive symptoms and neuropsychiatric/emotional symptoms, since the alteration is bidirectional:

Main digestive symptoms:

Emotional and cognitive symptoms:

Related disorders:

The most common imbalance is irritable bowel syndrome (IBS), which affects many patients and is characterized by visceral hypersensitivity and impaired motility. Others include functional dyspepsia, functional constipation, and cyclic vomiting syndrome.

If you experience persistent digestive discomfort combined with mood swings or prolonged fatigue, it is advisable to consult a professional.

How intestinal health affects cardiovascular health

Long-term evidence:

A 7-year follow-up study confirmed that the composition of the intestinal microbiota predicts the probability of developing new cardiovascular events, even in patients who have already suffered a heart attack.

How to protect both systems:

A healthy microbiota is achieved with a diet rich in fiber, regular physical activity and avoiding excess processed foods, which can reduce inflammation, improve blood pressure and regulate cholesterol.
