Hocine Lokchiri

General medicine21 years of experience

Dr. Hocine Lokchiri is a French consultant with over 20 years of experience in General and Emergency Medicine. He works with adults and children, helping patients with urgent symptoms, infections, sudden health changes and everyday medical concerns that require timely evaluation. His background includes clinical practice in France, Switzerland and the United Arab Emirates, which allows him to navigate different healthcare systems and manage a wide range of conditions with confidence. Patients value his calm, structured approach, clear explanations and evidence-based decision-making.

Online consultations with Dr. Lokchiri are suitable for many situations when someone needs quick medical guidance, reassurance or a clear next step. Common reasons for booking include:

  • fever, chills, fatigue and viral symptoms

  • headache, dizziness, migraine symptoms
  • stress-related symptoms, sleep disturbances
  • questions about test results and treatment plans

Many patients reach out when symptoms appear suddenly and cause concern, when a child becomes unwell unexpectedly, when a rash changes or spreads, or when it’s unclear whether an in-person examination is necessary. His emergency medicine background is particularly valuable online, helping patients understand risk levels, identify warning signs and choose safe next steps.

Some situations are not suitable for online care. If a patient has loss of consciousness, severe chest pain, uncontrolled bleeding, seizures, major trauma or symptoms suggesting a stroke or heart attack, he will advise seeking immediate local emergency services. This improves safety and ensures patients receive the right level of care.
