Whether you're a sufferer or worried about someone else, recognising and accepting that something's wrong is the first step.

The next step is to let someone you trust know what's happening. This could be a friend, relative, colleague, teacher, doctor or eating disorder professional.

From here, you can start getting some professional advice about what do next. If you haven't already spoken to one, you can contact your doctor or an specialist eating disorder organisation.

Though treatments vary, sufferers are normally offered counselling, therapy, diet and nutrition advice, access to support groups and, if needed, medication. And it's important to remember that suffers are only be taken into hospital if they're extremely ill.
