Frequently Asked Questions

Is this just jet lag?

Usually yes, especially in the first few days after a long flight. The doctor can rule out other causes if your symptoms don't fit the usual pattern.

Can I get sleeping pills?

A short-term sleep aid may be appropriate for some travelers. The doctor will discuss whether it's suitable for your situation.

How long does jet lag last?

Typically a few days to about a week, depending on how many time zones you crossed. Light exposure and a consistent schedule can help it resolve faster.

Can I get a medical certificate?

Yes, for travel insurance claims or airline documentation.

Will the doctor speak English?

Yes. All doctors seeing international patients are English-speaking, from first contact to the visit itself.

Should I go to a hospital?

Not usually. Jet lag and sleep trouble are rarely a hospital matter. A hospital referral is arranged only if an underlying condition needs care beyond a house call.
