Spa treatment by condition
Spa treatment for digestive conditions
Marienbad became famous for a water known for its effect on digestion even before the town’s first spa hotel existed. Treatment for digestive conditions draws on the drinking cure from sulphate-rich springs such as the Cross Spring, an individual diet programme and medical supervision over several weeks.
What is treated here
- Chronic and recurrent diseases of the stomach and bowel with persistent complaints despite standard therapy (position III/1)
- Crohn’s disease and ulcerative colitis (III/3)
- Chronic disease of the gallbladder and biliary tract with gallstone disease, and functional disorders of the biliary tract (III/4)
- Confirmed chronic pancreatitis and conditions after acute pancreatitis (III/8)
- Conditions after operations on the stomach, duodenum or bowel with post-operative symptoms confirmed by endoscopy
How the cure works
Initial examination on arrival day
The spa physician reviews gastroenterological findings — and endoscopy reports for post-operative conditions — and sets the spring, amount and timing of the drinking cure individually. Bring recent findings; without them no firm plan can be made.
Drinking cure and treatments in the morning
The day begins before breakfast at the spring with the cup and a slow walk; mineral baths, dry carbon dioxide baths or circulation-boosting procedures follow as prescribed. Rest lying down follows every treatment.
Diet and movement in the afternoon
The spa kitchen cooks to the prescribed diet system; the afternoon belongs to light movement, usually walking in the spa forests, which supports digestion.
Weekly check-up and final report
Once a week the physician adjusts the drinking plan and diet. At the end you receive a report for your own doctor and recommendations for eating at home.
Treatments used
- Drinking cure from the Cross Spring
- Sulphate-bicarbonate-sodium water with a mild laxative effect; amount, temperature and timing before meals are set individually by the physician.
- Drinking cure from the Ferdinand Spring
- Close in composition to the Cross Spring, used for the same digestive and metabolic indications.
- Spa-kitchen diet programme
- An individually assembled meal plan by diagnosis, for example gallstone disease or after stomach surgery.
- Dry carbon dioxide bath
- From the local Maria’s gas at 99.7% CO₂; supports relaxation and circulation as part of the daily plan.
- Physical therapy
- Electrotherapy or magnetic field therapy, prescribed as a supplement to the drinking cure and diet for some diagnoses.
- Walking
- Slow walking between sips at the spring and in the afternoon supports transit and is the recommended light activity for digestive diagnoses.
How long, and when
The length depends on the position of the indication list: for chronic stomach and bowel disease (III/1), 21 days of contributory spa care; for Crohn’s disease and ulcerative colitis (III/3), 21 days of comprehensive or contributory spa care; for chronic gallbladder and biliary tract disease (III/4), 21 days of contributory spa care; and for chronic pancreatitis (III/8), 21 days of comprehensive or contributory spa care — all covered by Czech public health insurance. Self-paying guests usually choose two to three weeks in consultation with the spa physician. Late summer and autumn are considered favourable, because holiday travel and irregular meals have usually made themselves felt by then, and the town is quieter after the main season.
What the studies show
For sulphate- and magnesium-rich mineral water in functional constipation, there is a double-blind randomised trial of 226 participants: after 14 days, 50% responded to treatment compared with 29% under control water; this was a French water of different composition (Dupont et al., 2019, Nutrition). A placebo-controlled trial of 106 participants found, after six weeks of half a litre of sulphate water daily, more spontaneous bowel movements and better consistency, with the primary endpoint only marginally significant (Bothe et al., 2015, Eur J Nutr). A 2025 British dietetic guideline therefore names water with a higher mineral content as one option for chronic constipation, with low to moderate certainty of evidence (Dimidi et al., 2025, J Hum Nutr Diet). Data on the gallbladder are sparser: in a controlled study of 40 participants, the fasting volume of the gallbladder shrank after twelve days of drinking a sulphate-bicarbonate water, alongside more frequent bowel movements; this was an Italian water of different composition and a small sample (Corradini et al., 2012, World J Gastroenterol). For Crohn’s disease, ulcerative colitis and chronic pancreatitis there are no comparable controlled studies of the drinking cure; treatment here rests on the experience of spa medicine and close medical supervision.
Experience and research under way
The drinking cure at the Cross Spring for digestive complaints is the oldest reason guests come to Marienbad; to this day the spa physician sets the amount, the spring and the timing individually. How the individual guest fares is not left unchecked: every treatment stay begins with an initial and ends with a final medical examination and a written final report, so the course is documented and the spa physician can adjust the plan along the way. Systematic evidence for spa medicine as a field is being built for the first time in a long while. The Institute of Spa Medicine and Balneology (Institut lázeňství a balneologie, v.v.i.), founded by the Karlovy Vary Region in 2019, has been running the first clinical study of this format in thirty years since 2026, together with Léčebné lázně Mariánské Lázně. It covers urological and nephrological diagnoses rather than the one described on this page: more than a hundred patients are examined before and after the spa stay for health status and quality of life, with prim. MUDr. Ladislav Špišák, CSc. as professional guarantor, and results are not yet available. The study runs within the Spa Research Centre project (2024 to 2027), funded by the Just Transition Operational Programme and working with the Czech Technical University, the University of West Bohemia and the Czech Academy of Sciences. What such work can produce is shown by the same institute’s earlier collaboration with the Marienbad spa houses: their joint study of spa rehabilitation after COVID-19 received the European Spas Association Innovation Award in 2021 in the Medical Spa Scientific Research category.
When a spa cure is not an option
- Acute gastrointestinal disease, acute infections, or an active worsening without prior specialist assessment
- Missing endoscopic or gastroenterological findings to confirm the diagnosis, especially for post-operative conditions
- Acute infectious disease, active cancer with signs of progression, marked cachexia
- Pregnancy, or an inability to manage personal care without a companion
Whether and in what form a spa cure is right for you is decided by the spa physician at the initial examination, based on your gastroenterological findings. This page provides information and does not replace medical advice.
Frequently asked questions
What is Marienbad known for as a spa town?
Marienbad has historically been known above all for its effect on digestion and metabolism. Over forty cold mineral springs rise within the town; the sulphate-bicarbonate-sodium Cross Spring, with a total mineral content of 9,845 mg/l, is the flagship for digestive indications.
Which spa cure helps with digestive complaints?
The Czech indication list lists digestive diseases as a separate group III, including chronic stomach and bowel complaints (III/1), Crohn’s disease and ulcerative colitis (III/3), and chronic gallbladder and biliary tract disease (III/4). Treatment combines a medically prescribed drinking cure with an individual diet programme.
How does the Cross Spring work on digestion?
The Cross Spring contains 3,130 mg/l of sulphate and 2,700 mg/l of sodium — the compound colloquially known as Glauber’s salt, which has a mild laxative effect. In a controlled study with a comparable sulphate-bicarbonate water, the fasting volume of the gallbladder shrank after twelve days, alongside more frequent bowel movements. The amount and timing are always set by the spa physician.
How long does a spa cure for digestive complaints last?
Under the indication list it is usually 21 days depending on diagnosis, with 14 days of contributory spa care sometimes possible on repeat stays. Self-paying guests usually choose two to three weeks — shorter stays tend to work more as convalescence.
Can I come for a spa cure with gallbladder disease?
Yes, chronic disease of the gallbladder and biliary tract is a separate position on the indication list (III/4). The requirement is a recent gastroenterological finding; suitability is assessed by the spa physician at the initial examination.
