Hyperparathyroidism is a condition in which the body produces excessive amounts of parathyroid hormone, which is responsible for maintaining a balance of Calcium and Phosphorus in the body. When we have too much of this hormone in our blood, calcium levels can climb too high which can cause health concerns like bone weakening and kidney stones. In this article, we will discuss the types, symptoms, causes, and treatment of hyperparathyroidism in-depth along with a few important questions.

Parathyroid Gland
[Click Here for Sample Questions]
The endocrine system's four tiny glands that regulate calcium levels in our bodies are known as parathyroid glands. Situated in the neck behind the thyroid gland, these glands are normally the size of a grain of rice. The glands are mostly responsible for controlling the calcium, phosphorous, and Vitamin D levels in our blood, in our bones, and throughout our bodies.
Parathyroid Gland
Parathyroid Hormone (PTH)
[Click Here for Previous Year Questions]
PTH (parathyroid hormone) also known as parathormone, is a hormone produced by the parathyroid glands. It regulates the amount of calcium in our blood and bones. Depending on the level of calcium in our blood, the release of PTH is turned on and off. The parathyroid glands, for example, will release more PTH if the blood calcium level drops. More PTH causes the bones to release calcium, which raises the blood calcium level.
The following functions are performed by the parathyroid hormone:
- The primary function is to regulate the levels of calcium in the blood to control the density of bones.
- Stimulates kidney cells to convert weaker forms of vitamin D into the most effective form for absorbing calcium from the intestines.
- Regulation of phosphate
- Calcium reabsorption from the proximal tubule, distal tubule, and renal collecting ducts is facilitated by this hormone

Types of Hyperparathyroidism
[Click Here for Sample Questions]
There various kinds of hyperparathyroidism are:
1. Primary Hyperparathyroidism
Primary hyperparathyroidism occurs when one or more parathyroid glands produce excessive amounts of PTH. A high level of PTH in the blood leads to a high level of calcium which can cause health issues like bone weakening, kidney stones, and loss of bone tissue. Non-threatening tumors and swelling on the gland can lead to this condition.
Primary Hyperparathyroidism
2. Secondary Hyperparathyroidism
Secondary hyperparathyroidism occurs when a condition outside of the parathyroid glands causes all of the glands to enlarge and become overactive and leads to excessive production of PTH hormone. High levels of PTH might have serious consequences for the person who is affected.
Secondary hyperparathyroidism can cause problems like bone disease and calcium built up in tissues and organs such as the heart and blood vessels.
3. Tertiary Hyperparathyroidism
This type of Hyperparathyroidism usually occurs in people with kidney ailments. The parathyroid gland during tertiary hyperparathyroidism becomes overactive and starts secreting excessive amounts of hormones even when the calcium levels are normal in the body.
Causes of Hyperparathyroidism
[Click Here for Previous Year Questions]
Hyperparathyroidism is caused by:
- Structural problems with parathyroid glands for instance a tumor or swelling of glands which result in an overactive parathyroid gland.
- Cancer of a parathyroid gland
- Abnormally low levels of vitamin D.
- Calcium deficiency that occurs when the kidney and intestine absorb calcium in huge quantities and remove calcium from the bones.

Symptoms of Hyperparathyroidism
[Click Here for Sample Questions]
In the case of early hyperparathyroidism, there may be mild symptoms such as:
- Appetite loss
- Pain in joints and bones
- Depression
- Weakening of muscles
- Fatigue
If hyperparathyroidism is more severe, the symptoms that may arise are:
- Feeling nauseous
- Urge to urinate
- Thirsty
- Constipation
- Feeling confused

Diagnosis of Hyperthyroidism

Various examinations and tests might be used to diagnose hyperthyroidism. These are:
- General eye, throat, and skin examinations.
- Blood tests to detect hormone levels of Thyroid-Stimulating Hormone, which include T3 & T4, and to detect calcium levels.
- Urine test to determine kidney functioning.
- Calculating the mineral density of bone through a bone density test.
- Detecting the presence of a swelling or a tumor through MRI, Thyroid, Ultrasound, and CT Scans.
Treatment of Hyperparathyroidism
[Click Here for Sample Questions]
Drugs, surgery, and blood phosphorus level regulation are all used to treat hyperparathyroidism. Anti-thyroid medications and radioactive iodine therapy are two pharmacological alternatives. In severe situations, surgical excision of parathyroid adenoma, i.e., non-malignant tumors, as well as the removal of the cancerous tumor, is sought.
Prevention of Hyperparathyroidism
- Practicing meditation for anxiety and stress.
- Avoiding alcohol, tobacco, and caffeine food products.
- Drinking more water.
- Regular exercise and walk for healthier bones.
- Intaking a balanced diet.

Things to Remember
- Hyperparathyroidism is a condition affecting the parathyroid glands, which are four pea-sized glands on or near the thyroid gland in the neck.
- Excessive secretion of the parathyroid hormones or PTH causes hyperparathyroidism symptoms which could be appetite loss, pain in joints and bones, depression, weakening of muscles, fatigue, etc.
- With secondary hyperparathyroidism, the treatment may include supplements of vitamin D and calcium.
- However, with primary hyperparathyroidism, surgery might be needed to remove the overactive parathyroid gland or glands in severe cases.
- The parathyroid glands are mostly responsible for controlling the calcium, phosphorous, and Vitamin D levels in our blood, in our bones, and throughout our bodies.

Ques. What are the functions of the parathyroid hormones [3 marks]
Ans. The functions of the parathyroid hormones are:
- Regulating the calcium levels in the blood
- Aiding the production of activated vitamin D
- Regulation of phosphate
Ques. What steps can be taken to prevent hyperparathyroidism? [5 marks]
Ans. Hyperparathyroidism can be prevented by:
- Practicing meditation for anxiety and stress.
- Avoiding alcohol, tobacco, and caffeine food products.
- Drinking more water.
- Regular exercise and walk for healthier bones.
- Intaking a balanced diet.
Ques. How does secondary hyperparathyroidism cause bone disease? [3 marks]
Ans. Bone turnover is high in those with hyperparathyroidism. This means that the cells that remove bone function faster than the cells that form new bone, resulting in weak and brittle bones. Bone pain and fractures are more likely as a result of this.
