About Prof. Dr Christian Berg

Prof. Christian Berg, MD, is a specialist in diabetology and head physician of the clinic for angiology, diabetology, and endocrinology at the Evangelical Hospital Mettmann.

The diabetes clinic, under the direction of Prof. Berg, offers diabetes therapy at the highest medical level and, according to the latest medical knowledge, helps each patient accept and manage diabetes.

State-of-the-Art in Diabetes Therapy - The Patient is the Focus

Professor Christian Berg has many years of experience in dealing with diabetes. He wants to encourage his patients to be the best therapist for themselves. Special attention is paid to the individual therapy wishes of those affected, which an experienced diabetes specialist asks about in a consultation to develop a unique treatment concept together.

Current diabetes therapy does not focus on the disease itself but on the patient and, in particular, on how they deal with the disease. This is because the patient's behavior is of the utmost importance in successfully coping with this metabolic disorder. For this reason, Prof. Berg and his team see it as their primary goal to explain the pathological processes plausible and practical, to make the patients experts on their disease. Then, with a sufficient understanding of the metabolic processes, patients can adopt health-promoting behaviors to reduce complications and late complications.

Diabetologists often hear from their patients that knowledge of their sugar metabolism makes it easier to manage their disease, enabling them to make healthier choices in everyday life.

New Medications: Diabetes Adjustment in Type 1 and Type 2 Diabetes

In the case of recently diagnosed type 1 or type 2 diabetes, inpatient admission is often advisable to adjust the blood glucose level that has gotten out of control with insulin. This allows prompt response to hypoglycemia in an emergency, and correct handling can be trained. After deciding on the ideal therapy mode based on the needs and activities of most adolescent patients, Prof. Berg and his team enable their patients to independently carry out the optimal insulin therapy during their inpatient stay.

Latest Technology: Glucose Sensors and Insulin Pump Settings

Together with the therapeutic team, Prof. Berg makes groundbreaking decisions with his patients, such as using an insulin pump. The focus of this form of therapy is on type 1 diabetics, but also type 2 diabetics. Even for the sometimes-complicated adjustment of these medical devices, inpatient admission is usually advised to ensure patient safety. The use of the pumps is intensively trained during the hospital stay. This includes handling technical problems, dose calculation, and pump breaks during sports.

New Drug-Assisted Weight Reduction and Severe Insulin Resistance

In the case of severe insulin resistance, usually in the context of a metabolic syndrome, blood glucose levels cannot be adequately controlled even by high insulin doses (more than 100 I.U. per day). Therefore, before a metabolic situation that is out of control threatens, an inpatient adjustment of the therapy concept is recommended. During the hospital stay, diabetes specialists offer their patients the option of participating in a so-called oat diet. In various studies, the need for insulin could be significantly reduced by increasing the proportion of oats in the diet. In addition, we offer medicinal aids for weight reduction, also for the longer-term outpatient course.

Acute Diabetic Foot

When suffering from diabetes, any acute foot problem is a difficult situation. Due to progressive sensory disturbances, load-related inflammation of the joints and bones often goes unnoticed, and wound healing issues frequently occur due to reduced blood flow to the tissues. As a result, the foot skeleton becomes unstable and collapses. Bizarre deformities of the foot develop, leading to extensive pressure damage and infection of the skin until amputation seems inevitable. Only early intervention can prevent such fatal complications.

Complex Metabolic Management in Desired Children/Pregnancy

Particularly in high-risk pregnancies after the age of 35, miscarriages, and in cases of unfulfilled desire to have children, metabolic situations that are out of control are frequently the center of the problem. In many cases, mother and child can be helped by clarifying and effectively treating these inhibitions.
