Prim. Univ. Prof. Dr. Ludwig Kramer FEBGH is a specialist in internal medicine, gastroenterology, and hepatology as well as internal intensive care medicine. He is married and the father of an adult son.
Prof. Dr. Kramer has over 30 years of national and international experience as an internist, gastroenterologist, hepatologist, endoscopist, and intensivist and scientist.


He has given over 500 lectures at national and international events and was a pioneer in extracorporeal therapies for liver failure at AKH after a study visit in 1996 at the Liver Unit of King's College Hospital in London.
His habilitation in internal medicine took place in 2002; subsequently, he was awarded the title of university professor.


Prof. Dr. Kramer has received prestigious awards for his research, including the Billroth Prize, Paracelsus Prize, and the Vienna Health Prize. In 2011, he was recognized as the best speaker at ICED Alpbach.
At the Medical University of Vienna, he held academic positions as curriculum coordinator and member of the study commission for human medicine. From 2005-2007, he was a EUROREG scholar (university diploma in clinical study management).


After being appointed as the head of the 1st Medical Department at the Hietzing Clinic in March 2008, he was, among other roles, a board member of the Austrian Society for Gastroenterology and Hepatology (ÖGGH), research representative of the Vienna Medical Chamber, head of the nutrition team, and a member of the drug commission in Hietzing, as well as a long-standing Austrian representative of the European Board of Gastroenterology and Hepatology (EBGH), engaged in the national development and international networking of his field.


In 2015, he became the first Austrian to pass the European specialist examination in gastroenterology and received the fellowship of the EBGH in 2017.
Despite his intensive national and international activities (Chair, CME committee, member of the EBGH Executive Committee 2014-23, elected primary care physician spokesperson 2015-23), Prof. Dr. Kramer has always been tirelessly committed to patient care at the bedside. He has shared his knowledge with countless doctors in training, students, and affected individuals. He has also been the vice president of the patient initiative FruLak & Co. (fructose, lactose, histamine intolerance) for many years.


With the scientific organization of the "Vienna Intestinal Day" in Schönbrunn 2013 and the "Digestion Day" at the Vienna City Hall in 2017/2019, he was able to inspire over 8500 participants on topics related to intestinal health and the intestinal microbiome. His activities also showed great interest in health policy, such as working in the "Task Force for the Prevention of Obesity-Promoting Living Environments" and "Health Visions for Vienna" and as a commissioner in the Vienna Health Network for non-invasive respiratory support in COVID-19 pneumonia in 2021.


His medical focus is diverse and includes the clarification and treatment of diseases of the digestive organs (esophagus, stomach, intestines, liver, bile ducts, and pancreas) as well as functional diseases, infections, and complaints of the gastrointestinal tract. His high medical expertise is combined with a solid knowledge of modern imaging diagnostics and an open view of the limits of conventional medicine and the use of alternative healing methods. Nutritional medicine and phytotherapy are always a pillar of his treatment concepts.


The interdisciplinary collaboration in TRINICUM is particularly beneficial for him.
