Thermal Treatment for Gastritis

Gastritis is a frequent pathology of the digestive system, characterized by inflammation of the stomach lining (mucosa), which can present in either an acute or chronic form. It usually manifests through symptoms such as epigastric pain, bloating, nausea, vomiting, and digestive difficulties. Its causes are varied, including Helicobacter pylori infection, the use of non-steroidal anti-inflammatory drugs (NSAIDs), excessive consumption of alcohol and tobacco, dietary factors, and autoimmune diseases.

In addition to conventional medical treatment and dietary measures, thermal treatment emerges as a complementary approach with recognized benefits in controlling symptoms and improving digestive function, especially in cases of chronic gastritis.

What does thermal treatment for gastritis consist of?

Thermal treatment for gastritis consists of the therapeutic use of natural mineral waters which, due to their specific chemical composition, can help relieve symptoms. It is based on the use of thermal waters, primarily administered orally, a practice known as hydropinia (controlled oral ingestion of thermal water).

These waters exert a regulatory action on gastric secretion, protecting the stomach lining and contributing to the reduction of inflammation.

In addition to the ingestion of thermal water, the therapeutic program can include immersion baths with hydromassage, relaxation techniques, and education for digestive health with nutrition consultations, integrating into a global approach to the patient.

How does thermal treatment work for gastritis?

The action of thermal treatment on gastritis results essentially from the chemical and biological effects of mineral-medicinal waters on the digestive system.

Sodium bicarbonated waters, such as those at Termas de Chaves, help neutralize excess gastric acidity, reducing symptoms.

The regular and controlled ingestion of thermal water also stimulates gastric motility and contributes to a more balanced digestion. In parallel, the thermal environment and the detachment from daily stress factors—frequently involved in the worsening of pre-existing gastritis—have a positive impact.

Hydropinia should be performed on an empty stomach, either 15–30 minutes before or 3 hours after meals daily. Generally, it starts with a smaller amount and progressively increases to a stable dose that will remain until the end of the treatment.

In thermal spas, such as Termas de Chaves, with indications for digestive tract pathologies, the treatment is always prescribed individually, following a specialized medical evaluation.

Benefits of thermal treatment for gastritis

Thermal treatment presents several benefits in the management of gastritis, namely:

• Relief of gastric pain and discomfort;

• Reduction of acidity and burning sensations;

• Decrease in stomach lining inflammation;

• Improvement of digestion and food tolerance;

• Reduction in the need for symptomatic medication, in some cases;

• Promotion of general well-being.

These effects contribute to a significant improvement in the patient's quality of life, especially in situations of chronic gastritis.

Evidence and integration into the therapeutic plan

Medical hydrology has recognized for several decades the role of thermal treatment in functional and inflammatory diseases of the digestive system. Clinical studies demonstrate the benefits of using thermal water in regulating gastric secretion and improving symptoms.

It is important to emphasize that thermal treatment does not replace conventional medical treatment or gastroenterological surveillance. It should be understood as a therapeutic complement, integrated into a global plan that includes appropriate medication, correction of dietary habits, and control of risk factors.

Care and recommendations before starting thermal treatment

Before starting a thermal treatment program for gastritis, a medical evaluation by a hydrologist physician is essential, in coordination with the family doctor or gastroenterologist.

The indication depends on the type of gastritis, the phase of the disease, the existence of an active ulcer, or other associated pathologies. In situations of acute gastritis, digestive hemorrhage, or an active ulcer, thermal treatment may be contraindicated.

When properly indicated, thermal treatment constitutes a natural, safe, and effective option, and can be co-funded by the National Health Service (SNS) and various health subsystems, standing as an important resource in the integrated treatment of gastritis.
