Andrei Popov

General medicinePain medicine7 years of experience

Dr. Andrei Popov is a General Practitioner with specialized training in chronic pain. He provides online consultations for adult patients in Spain and other European countries.

Dr. Popov understands that seeking help with weight-related concerns or pain that has persisted for months can be difficult. Many patients come to him after trying different approaches without feeling truly heard. During the consultation, the doctor creates a comfortable and supportive, non-judgmental environment where the patient’s medical history can be discussed in detail, questions can be answered, and the next steps can be decided together.

Weight Management and Metabolic Health

Dr. Popov can help assess overweight, obesity, and related conditions such as hypertension, diabetes, or metabolic disorders. During the consultation, the patient’s medical history, test results, current medications, and previous treatments will be reviewed.

If you would like to learn about possible medication options or have already started treatment, the doctor can assess your situation, review the effectiveness and tolerability of the therapy, and clearly explain its benefits, potential risks, and alternatives.

Not every patient requires the same treatment. A consultation does not guarantee a prescription — it provides an objective medical assessment and a plan tailored to your individual situation.

Pain and General Medicine

You can also consult Dr. Popov regarding:

* chronic pain, migraines, neuralgia, and fibromyalgia;

* back, neck, lower back, or joint pain;

* hypertension, diabetes, and follow-up of chronic conditions;

* review of test results, medical reports, and current treatment;

* preventive medicine and a second medical opinion.

How the Consultation Works

The video consultation lasts up to 30 minutes. The doctor will listen carefully, review the information you provide, and explain the next steps in clear and understandable language.

If additional tests, an in-person consultation, or urgent medical care are required, the doctor will inform you directly.

Dr. Popov’s goal is to make sure the patient feels heard and leaves the consultation with a clear understanding of their condition and the next steps they can take.
