Instructions from your own surgical or prescribing team take priority over this general guide. Contact local emergency care for severe or rapidly worsening symptoms.
Key takeaways
- The IOC aftercare portal is a verified-patient pathway for routine nutrition, follow-up planning and coordination support.
- Registration is not open to the public: request access from Mustafa and wait for the team to verify your patient record.
- The portal is not an emergency service. Severe or rapidly worsening symptoms require local emergency medical care.
What is the IOC aftercare portal?
The IOC patient aftercare portal brings routine post-treatment information and contact routes into one clearer pathway. Depending on your individual care plan, it can help you find staged nutrition guidance, planned follow-up dates, blood-test reminders and the correct coordination contact after you return home.
It supports the written discharge and follow-up plan supplied by your clinical team. It does not replace your surgeon, bariatric dietitian, GP, local hospital or emergency services, and it should not be used to self-diagnose a new symptom.
Who can register?
Portal access is intended for confirmed and verified Istanbul Obesity Center patients. There is no public sign-up form because the medical coordination team must match each request to the correct patient record and stage of care before issuing a personal access link.
If you are still researching treatment, use the free assessment route first. If your treatment is confirmed or you are already an IOC patient, you can request portal access from Mustafa using the official contact button on this website.
How to request registration and access
Use the Request secure access button in the patient portal section of the IOC website. It opens the official WhatsApp contact for Mustafa with a prepared message. Send the request from the telephone number recorded in your patient file whenever possible.
The coordination team will verify your details and tell you the next step. The exact sign-in instructions are supplied with your personal link, so do not follow registration links posted by another patient or an unofficial social-media account.
- State your full name and that you are requesting aftercare portal access.
- Provide the treatment date or planned treatment date if the coordinator asks for it.
- Wait for confirmation that your patient record has been matched.
- Open only the personal link sent through an official IOC contact.
- Keep the link and any password or verification code private.
What can I use it for?
The portal is designed for routine, non-emergency aftercare. The information visible to you depends on your treatment and written plan; not every patient follows the same nutrition stage, medicine schedule or blood-test timetable.
- Review the nutrition stages supplied by Bariatric Dietitian Aylin Demir.
- Check planned follow-up points, blood tests and important reminders.
- Find the appropriate routine contact for the coordination team.
- Keep your written discharge and longer-term follow-up information easier to find.
- Request help when a routine document or access link is missing.
Before your first login
Keep your discharge summary, operation information, medicine list and personal nutrition plan nearby. Check that your name, telephone number and planned procedure or treatment date match the information held by the coordination team.
Use a private device and a secure connection. Do not forward your access link to patient groups, friends or relatives. If you want a relative to help manage your aftercare, ask the coordination team how consent and access should be recorded rather than sharing your own credentials.
If the link is lost or does not work
Do not create a second identity or use another patient’s link. Contact Mustafa through the official IOC WhatsApp number, explain that access has been lost or is not working and allow the team to verify your record before a replacement link is issued.
Tell the team if your telephone number, email address or country of residence has changed. Never send passwords or verification codes to an account that cannot be confirmed as an official IOC contact.
When not to wait for the portal
The portal and WhatsApp contacts are not emergency services and messages may not be read immediately. Seek urgent local medical help for severe or increasing abdominal pain, chest pain, breathlessness, a fast heart rate, fever, fainting, significant bleeding, one-sided leg swelling, repeated vomiting or inability to keep fluids down.
Follow the urgent-care instructions in your discharge documents. If you attend a local hospital, take your English discharge summary, operation record, medicine list and the surgeon and hospital contact details with you.
Portal support and lifelong follow-up are different
IOC’s current gastric sleeve pathway includes one year of remote dietitian follow-up for eligible patients. Bariatric health monitoring continues beyond a commercial support period: arrange the longer-term annual reviews, blood tests and medicine or supplement checks recommended for your procedure with the appropriate clinicians in your home country.
Use the portal to support continuity and organisation, but keep your GP and local healthcare team informed about your operation and provide them with your discharge documents.
Request your secure aftercare access
Return to the patient portal section and contact Mustafa through the official access-request button.

Can anyone create an aftercare portal account?
No. Access is issued to confirmed, verified IOC patients after the medical coordination team matches the request to the correct patient record.
How do I receive my login link?
Use the official Request secure access button and contact Mustafa. After verification, the coordination team supplies your personal link and the applicable sign-in instructions.
Can I share my portal link with the support group?
No. A personal access link, password or verification code should not be posted in a group or forwarded to another patient.
Can I use the portal for an emergency?
No. Seek local emergency medical care for severe or rapidly worsening symptoms and follow the urgent-care plan in your discharge documents.
What if I change my telephone number?
