A health clinic may not be the best place to treat a particular illness or condition. However, it can be a great place to start when seeking care because the personnel will certainly be willing to recommend a specialist for your medical problem. Don't be afraid to ask.
The health clinic isn't just a place to go when you're ill: you can also get tips on how to eat well, how to manage a diet, how to lose weight, and how to stay healthy in general. Although these topics may not rate the attention of a doctor, and nurse should be willing to answer your questions.
