FAQ

These FAQs come from real patients seeking medical assistance through Bookimed. Answers are given by experienced medical coordinators and trusted clinic representatives.

Which Polish medical specialist focuses specifically on treating obesity?

Polish obesity treatment focuses on two main specialists: an obesitologist for medical management and a bariatric surgeon for operations. These experts are often certified by the Polish Association for the Study on Obesity (PTLO). They address obesity as a complex chronic metabolic disease rather than just a lifestyle issue.

Bariatric surgeons. Experts like Dr. Grzegorz Kowalski perform weight loss operations including sleeve gastrectomy and bypass.
Bariatric fellowships. Specialists like Dr. Artur Raiter complete advanced training in the USA to master techniques.
Minimally invasive methods. Prof. Piotr Major uses laparoscopic surgery to ensure low post-surgery infection rates and recovery.
Non-invasive specialists. Dr. Michal Kazanowski uses the Allurion Programme, which helps patients lose weight without surgery.

Bookimed Expert Insight: While many doctors treat metabolic issues, top Polish specialists at KCM Clinic hold memberships in the International Federation for the Surgery of Obesity (IFSO). This ensures they follow global protocols for safety. Patients should look for surgeons like Dr. Artur Raiter, the only specialist in Poland performing no-incision endoscopic sleeve gastroplasty.

Patient Consensus: Patients prefer a dedicated obesitologist over a general endocrinologist to ensure the doctor directly manages obesity. They value specialists who focus on hunger levels and blood work rather than just weight. Clear, step-by-step treatment plans help patients avoid the frustration of vague advice.

What questions should I ask a Polish doctor during an initial obesity consultation?

When consulting a Polish obesity specialist, ask about diagnostic blood tests for insulin resistance and hormonal screening. Inquire if they suggest minimally invasive surgery – like the 1,600+ procedures performed by Prof. Piotr Major – or non-invasive options like the Allurion gastric balloon.

Diagnostic screening. Ask which hormones and metabolic markers they screen to rule out secondary obesity causes.
Procedural experience. Confirm how many bariatric surgeries or endoscopic treatments the doctor has successfully performed.
Multidisciplinary support. Inquire if they coordinate care with dietitians and psychologists for long-term behavioral success.
Follow-up structure. Ask for a concrete three-month goal and the frequency of regular progress monitoring.

Bookimed Expert Insight: Patients in Poland can choose between surgical and non-surgical specialists within the same facility. For example, KCM Clinic offers both high-volume surgeons like Dr. Grzegorz Kowalski and experts like Dr. Michal Kazanowski, who focuses on the non-invasive Allurion stomach balloon.

Patient Consensus: Patients felt more prepared when they asked if the visit would end with a specific medical plan or a diagnostic referral. They also noted that discussing emotional eating patterns early helped them feel more supported throughout the treatment.

Under what criteria will a doctor in Poland approve a patient for bariatric surgery?

Polish doctors approve bariatric surgery for patients with a BMI of 40+ or 35+ with obesity-related conditions. Qualification requires proof of failed weight loss attempts and clearances from dietitians and psychologists to confirm readiness for long-term lifestyle changes.

BMI thresholds. A BMI over 40 qualifies automatically for most surgical weight loss procedures.
Associated comorbidities. Patients with BMI 35–40 need documented conditions like diabetes or sleep apnea.
Behavioral readiness. Specialists require a 5% preoperative weight loss to prove commitment to the program.
Medical clearances. Success depends on mandatory sign-offs from an anesthesiologist, dietitian, and bariatric psychologist.

Bookimed Expert Insight: Data shows that top Polish specialists like Prof. Piotr Major at KCM Clinic focus on minimally invasive laparoscopic techniques. Choosing a surgeon with 1,600+ procedures often ensures lower infection rates and faster recovery. His experience helps patients navigate the strict Polish qualification criteria more efficiently due to established surgical workflows.

Patient Consensus: Patients mention that surgery discussions only become realistic once you provide proof of previous diet attempts. Many suggest bringing a detailed timeline of past weight loss efforts to help surgeons assess medical risk.

Are psychological and dietary evaluations required by doctors before surgical procedures?

Bariatric doctors in Poland require psychological and dietary evaluations as standard protocol before weight loss surgery. These screenings assess emotional readiness and provide nutritional education. Specialists such as Dr. Grzegorz Kowalski and Prof. Piotr Major use these results to plan safe, long-term metabolic care.

Psychological screening. Doctors assess eating habits and stress coping to confirm surgery readiness.
Dietary counseling. Specialists teach meal structure and protein goals for post-surgical healing.
Behavioral assessment. Evaluations identify patterns like binge eating that might affect results.
Lifestyle education. Sessions explain how surgeries—like gastric sleeve—require lifetime dietary commitment.

Bookimed Expert Insight: In Poland, top specialists like Prof. Wojciech Lisik lead programs where evaluations are not just tests but part of a comprehensive care model. At KCM Clinic, specialists combine these screenings with precise diagnostics like Price on request to Price on request for hormonal profiling. This integrated approach helps doctors choose the right technique, such as Dr. Artur Raiter’s no-incision gastroplasty, based on a patient's emotional and physical profile.

Patient Consensus: Patients felt the psychological visit was a readiness check rather than a judgment of their character. Many were surprised by the focus on hydration and portion sizes during the dietary sessions. These evaluations made them realize surgery is only a start and helped them feel more prepared for the routine after the procedure.

What surgical procedures are most commonly performed by Polish bariatric teams?

Polish bariatric teams primarily perform sleeve gastrectomy and gastric bypass using minimally invasive laparoscopic techniques. Specialists like Dr. Piotr Major at KCM Clinic emphasize these procedures to reduce stomach volume and hunger. They also offer non-invasive options such as the Allurion balloon and revision surgeries for complex cases.

Sleeve gastrectomy. This common procedure removes approximately 80% of the stomach to limit food intake.
Gastric bypass. Specialists reroute the digestive system to provide a stronger metabolic effect for patients.
Endoscopic sleeve gastroplasty. Dr. Artur Raiter pioneered this no-incision approach for patients seeking non-surgical alternatives.
Gastric balloon. Dr. Michal Kazanowski uses the Allurion program for non-invasive treatment without traditional surgery.

Bookimed Expert Insight: Patients in Poland can access specialized no-incision techniques introduced by specialists like Dr. Artur Raiter. While sleeve gastrectomy is the standard, these non-surgical alternatives provide effective options for those avoiding traditional incisions. This variety allows teams to tailor procedures to individual metabolic needs and personal recovery preferences.

Patient Consensus: Patients were surprised by the extensive pre-op testing and diet changes required before scheduling their surgery. They noticed that daily work like maintaining protein intake is more demanding than they expected. Many recommend asking which specific operation is best for your long-term food tolerance and vitamin needs.
