What are the parathyroid glands and why do they fail?
Although their name sounds similar to the thyroid, the parathyroid glands have a completely different function. They are four small glands, about the size of a grain of rice, located in the neck next to the thyroid gland.
Their mission is vital: to regulate calcium levels in the blood, bones, and nervous system by producing parathyroid hormone (PTH).
The problem arises when one or more of these glands grow excessively (usually what we know as a parathyroid adenoma) and begin to produce PTH uncontrollably. This is known as primary hyperparathyroidism.
The Dangers of High Calcium (Hypercalcemia)
It’s not just a number on a lab report. An excess of calcium or PTH in the blood can cause:
- Chronic fatigue, tiredness, and muscle weakness
- Bone pain or signs of premature osteoporosis
- Recurrent kidney stones
- Difficulty concentrating or "brain fog"
- Reflux or abdominal pain
- Hypertension (HTA) and cardiovascular impact

Hyperparathyroidism
Despite being a condition that is sometimes underdiagnosed, it is much more common than people think. The statistics are clear: over the course of their lifetime, 1 in 100 people will develop a tumour in one of their parathyroid glands.
This incidence increases significantly in a specific profile: 1 in 50 women over the age of 50 will suffer from this condition.
In the vast majority of cases, it is a parathyroid adenoma: a benign (non-cancerous) tumour that nevertheless behaves in a "rebellious" manner. This tumour continuously produces excess PTH hormone, raising calcium and/or PTH levels in the blood and giving rise to primary hyperparathyroidism.
Our Approach: Minimally Invasive Surgery
Unlike traditional approaches, our philosophy focuses on minimal aggression and maximum safety. Current parathyroid surgery allows all patients to benefit from advanced techniques.
Treatment Benefits
Thanks to the expertise of Dr. Constanza Ballesta we perform surgeries characterised for:
- Small incisions: Excellent aesthetic results, almost imperceptible over time.
- Light anaesthesia: Reducing recovery times and associated risks.
- Quick recovery: Most patients return to their normal lives in record time.
- Recovery rate above 98%: A percentage that can only be achieved by highly specialised surgeons.
Comprehensive Diagnosis
For surgery to be successful, the preliminary study must be extremely rigorous. At Turó Park Clinics, we integrate,

| Diagnostic Test | Function | Benefit for the patient |
|---|---|---|
| Complete analysis | Confirm parathyroidsim | Accuracy in the initial diagnosis |
| 4D/High resolution Ultrasound | Location | Guide for minimal incision |
| Sestamibi Scintigraphy | Location | Identify overactive glands |
| Intraoperative PTH | Real time confirmation | Confirm healing before closing |

Post-operative care: What to expect after surgery?
One of the biggest concerns is recovery. By using minimally invasive techniques, the post-operative period is very manageable.
First Hours
You will feel almost immediate relief from the "brain fog". More balanced calcium levels will have a revitalising effect.
Pain management
The pain is comparable to that of a mild pharyngitis and can be easily controlled with common painkillers.
Scarring
We use transparent intradermal sutures that we remove to reduce inflammation. After a few months, the scar is camouflaged by the natural folds of the neck.
Temporary Supplements
During the first few weeks, we may prescribe calcium and vitamin D while the other three glands (which were "dormant") become active again.
