I am 40, male. Is high salt intake linked to stomach cancer?

Question

Hello doctor,

As a 40-year-old male with a history of hypertension, I am troubled by the potential connection between excessive salt intake and the risk of stomach cancer. Given my challenges in adhering to a low-sodium diet due to dietary habits and preferences, I am turning to you for professional guidance.

Could you please provide more detail on the correlation between salt consumption and the onset of stomach cancer? Are there specific mechanisms or pathways through which elevated salt intake might contribute to the development of this type of cancer?

Kindly help.

Hello,

Welcome to icliniq.com.

I can understand your concern.

High salt intake has been linked to an increased risk of stomach cancer, particularly in populations with a diet high in salty and preserved foods. Consuming high amounts of salt can lead to the formation of Nitrosamines in the stomach, which are known carcinogens. It is recommended to limit salt intake and opt for a balanced diet rich in fruits, vegetables, and whole grains to reduce the risk of stomach cancer and other health issues.

Alterations in the composition of H. pylori (Helicobacter pylori) strains. Among the numerous mechanisms by which a high-salt diet might enhance gastric cancer risk, high-salt conditions in the stomach may have direct effects on H. pylori, affecting the expression of different types of genes.

One of them is the promotion of gastric epithelial proliferation, oncogenes, and DNA damage via cytotoxin-associated gene A (CagA), vacuolating toxin A (VacA), and outer membrane proteins (OMPs) such as blood group antigen-binding adhesin (BabA) and sialic acid-binding adhesin (SabA)

I hope this information helps.

Thank you.
