Almost always start with your GP. They can diagnose the most common causes of dehydration directly, order initial investigations, and make an informed referral to the right specialist if needed. Going directly to a specialist without GP input often results in an incomplete workup.
What should I tell my doctor about my dehydration?
Tell your doctor: when it started, how it has changed, severity (1–10), what triggers it, what makes it better or worse, any associated symptoms, all medications and supplements, and your family history. The more specific you are, the faster the diagnosis.
What if my doctor cannot find the cause of my dehydration?
If a cause is not found after initial evaluation, ask for: specialist referral, additional investigations (blood tests, imaging, or specialist tests), or a second opinion. Persistent unexplained dehydration deserves thorough investigation — advocate for yourself if you feel concerns are being dismissed.
