A 25-year-old male presents to the endocrine clinic due to treatment-resistant hypertension
A 25-year-old male presents to the endocrine clinic due to treatment-resistant hypertension. He has remained well with no headaches, palpitations, sweats or chest pain symptoms. He had felt fatigued for the past 6-8 months but felt this was a result of returning to university. He recalls that his father and grandmother both had issues with hypertension since their early adulthood.

| Ur | 6.4 | 2.5 – 7.8 mmol/L |
| Cr | 90 | 60-100μmol/L |
