Absolutely would suggest getting an appointment with your doctor before doing any detoxes, taking any supplements or making dietary changes. Your body showing a significant change in water retention can be a number of factors (anything from a lymphatic flow issue, reflect kidney health, electrolyte balances, hydration etc.). I can even happen from being at altitude from being on a long flight. A doctor can run the appropriate test and diagnostics to get a better idea of causation - but do not put it off, its always better to observe your body and get the data from a medical professional.
