Introduction
Hypocalcaemia is a medical condition characterized by abnormally low levels of calcium in the blood. Calcium is an essential mineral that plays a crucial role in various bodily functions, including muscle contraction, nerve transmission, and bone health.
Causes of Hypocalcaemia
- Hypoparathyroidism: One of the most common causes of hypocalcaemia is the underproduction of parathyroid hormone (PTH) by the parathyroid glands. PTH is responsible for regulating calcium levels in the body. When these glands don’t function properly, calcium levels can drop.
- Vitamin D Deficiency: Vitamin D plays a vital role in the absorption of calcium from the intestines. Insufficient vitamin D intake or inadequate exposure to sunlight can lead to hypocalcaemia.
- Kidney Disorders: The kidneys are responsible for filtering and excreting waste products, including excess calcium. Kidney disorders, such as chronic kidney disease, can disrupt this process, leading to low calcium levels.
- Medications: Certain medications, like diuretics, anticonvulsants, and bisphosphonates, can interfere with calcium absorption or increase calcium excretion, potentially causing hypocalcemia.
- Malabsorption Disorders: Conditions such as celiac disease, Crohn’s disease, or gastric bypass surgery can impair the body’s ability to absorb calcium from the digestive tract.
- Alcoholism: Excessive alcohol consumption can hinder calcium absorption and disrupt the functioning of the parathyroid glands.
Symptoms of Hypocalcaemia
- Muscle Cramps and Spasms: Low calcium levels can lead to muscle irritability, resulting in painful cramps and spasms, especially in the hands and feet.
- Numbness and Tingling: Individuals with hypocalcemia may experience numbness and tingling sensations, known as paresthesia, in the extremities or around the mouth.
- Fatigue: Calcium is essential for muscle and nerve function. A lack of calcium can lead to muscle weakness and overall fatigue.
- Joint Pain: Hypocalcemia may cause joint pain, making movements uncomfortable and painful.
- Seizures: In severe cases, hypocalcaemia can trigger seizures due to abnormal nerve signalling.
- Abnormal Heart Rhythms: Calcium is crucial for maintaining a regular heart rhythm. Low calcium levels can lead to palpitations and arrhythmias.
- Brittle Nails and Dry Skin: Calcium deficiency can affect the health of your skin and nails, making them brittle and dry.
- Mental Confusion: Hypocalcemia can also affect cognitive function, leading to confusion, memory problems, and mood changes.
Hypocalcaemia is a medical condition that should not be taken lightly, as it can have serious health implications. Understanding its causes and recognizing its symptoms is the first step in management.
Diagnosis of Hypocalcaemia
Hypocalcaemia, a condition characterized by low levels of calcium in the blood, can lead to various health issues if left untreated.
- Blood Tests: A blood test is the primary diagnostic tool for hypocalcaemia. It measures the concentration of calcium in the blood. Levels below 8.5 milligrams per decilitre (mg/dL) are generally considered low.
- Ionized Calcium Test: In some cases, an ionized calcium test may be performed to measure the amount of calcium that is biologically active. This provides a more accurate assessment of calcium status.
- Parathyroid Hormone (PTH) Levels: Doctors often measure PTH levels to determine if hypocalcaemia is due to a problem with the parathyroid glands, which regulate calcium balance.
- Vitamin D Levels: A blood test for vitamin D levels helps identify whether a deficiency is contributing to hypocalcaemia.
Treatment for Hypocalcaemia
- Calcium Supplements: Calcium supplements in the form of calcium carbonate or calcium citrate are commonly prescribed to raise blood calcium levels. These are usually taken with vitamin D supplements for optimal absorption.
- Vitamin D Supplements: If hypocalcaemia is linked to a vitamin D deficiency, vitamin D supplements are essential to enhance calcium absorption.
- Intravenous Calcium: In severe cases or when oral supplements are not effective, healthcare providers may administer calcium intravenously.
- Treatment of Underlying Causes: Addressing the underlying cause of hypocalcaemia, such as treating kidney disorders or adjusting medications, is crucial for long-term management.
Prevention of Hypocalcaemia
- Dietary Changes: Ensure a diet rich in calcium-containing foods, including dairy products, leafy greens, fortified cereals, and nuts. This can help prevent calcium deficiency.
- Adequate Vitamin D: Sunlight is a natural source of vitamin D. Spend time outdoors and consume foods fortified with vitamin D to maintain optimal levels.
- Limit Alcohol: Excessive alcohol consumption can interfere with calcium absorption, so moderation is key.
- Medication Management: If you are on medications that can lead to hypocalcemia, consult your healthcare provider for alternative options or additional supplements.
- Regular Check-ups: Routine medical check-ups can help detect early signs of hypocalcemia or underlying conditions that may contribute to it.
Diagnosing, treating, and preventing hypocalcemia is essential for maintaining overall health. Early diagnosis through blood tests, followed by appropriate treatment with calcium and vitamin D supplements, can effectively manage this condition.
To prevent hypocalcemia, focus on a balanced diet, adequate sun exposure, and responsible alcohol consumption. Regular check-ups with a healthcare provider can ensure that any potential issues are identified and addressed promptly, promoting optimal calcium balance and overall well-being.

If you or someone you know is experiencing any of the symptoms mentioned above, it is essential to seek medical attention promptly. Early diagnosis and treatment can help restore normal calcium levels and improve overall well-being.
