Produktbeschreibung

Hypercalcemia is too much calcium (above 10.4 mg/dL or 2.6 mmol/L) in the blood.
Normal blood Calcium varies from 8.4 to 10.4 mg/dL (2.25-2.6 mmol/L).
In hypercalcemia, just over 50% of the circulating calcium is protein bound and the level of circulating protein, mainly albumin, must also be considered in making this measurement.
The value for serum calcium is often given by laboratories as both an uncorrected value and a corrected value which has permitted for changes in albumin levels.
It is only the ionized (unbound) calcium which is important the body, taking part in cellular activities such as neuromuscular contraction, coagulation and other cellular activities.
Raised calcium concentrations are linked with significantly decreased quality of life and higher healthcare consumption.
Calcium has an important part to play in the effective working of the majority of cells in the body and it is therefore essential that the optimal level be maintained by the body.
A decrease in serum calcium can stimulate parathyroid hormone (PTH) release which may then raise bone resorption, increase renal calcium reabsorption, and activate renal conversion of 25-hydroxyvitamin D3, to the active 1,25-dihydroxyvitamin D3, which then will raise intestinal calcium absorption.
These mechanisms restore the serum calcium to normal and restrict further production of PTH and 1,25-dihydroxyvitamin D3
Parathyroid hormone (PTH) and Vitamin D help organize calcium balance in the body.
PTH is produced by the parathyroid glands.
Vitamin D is received when the skin is exposed to sunlight, and from dietary sources.
The most frequent cause of high calcium blood level is excess PTH secreted by the parathyroid glands happening due to:
1. An enlargement of one or more of the parathyroid glands.
2. A growth on one of the glands.
Most of the time, these growths are benign.
3. Calcium blood level may also be high if the body is low on fluids or water.
Other disorders can also cause hypercalcemia:
1. Certain kinds of cancers, such as lung and breast cancer, or cancer that has spread to the organs.
2. Too much vitamin D in the system.
3. Being on bed rest for a long time.
4. Being bed-bound (or not being able to move) for a long period of time.
5. Too much calcium in the diet.
The disorder is most often diagnosed at an early stage using routine blood tests.
Most people are asymptomatic.
Symptoms due to high calcium level may be varying, dependent on the cause and the duration the disorder has been present:
1. Digestive symptoms, such as nausea or vomiting, poor appetite, or constipation
2. Raised amount of thirst or more frequent urination, due to changes in the kidneys
3. Muscle weakness or twitches
4. Alterations in how the brain works, such as feeling tired or fatigued or confused
5. Bone pain and long-term spine alterations, if the bones have become thinner or weaker
An accurate diagnosis is required in hypercalcemia
Investigations
1. Serum calcium and phosphate
2. Serum PTH
3. Serum PTHrP (PTH-related protein)
4. Serum alkaline phosphatase
5. Blood albumin and proteins
6. Urine calcium and phosphate
Acute hypercalcemia is a medical emergency because of its effect on the heart rhythm.
1. Immediate treatment of intravenous isotonic saline and replacement of salt in a hospital raising the circulating volume with 0.9% saline
2. A powerful diuretic such as frusemide to reduce fluid overload
3. Phosphate intravenously or orally can also be effective to decrease the calcium from the blood
4. After rehydration, bisphosphonates, Salmon Calcitonin, steroids decrease the high blood calcium
People with primary hyperparathyroidism may need surgery.

Autorenporträt

Dr. Kenneth Kee is a well-known medical doctor from Singapore who has been practicing medicine since 1972.
He graduated from the University of Singapore and furthered his studies with a Master of Science in Health Management in 1991, followed by a Ph.D. in Healthcare Administration in 1993.
Dr. Kee established Kee Clinic in 1974, located in the Holland Drive area of Singapore. The clinic has been a prominent feature of the community, offering general medical services for 5 decades.
Dr Kee also served his country Singapore as a national service police Inspector at night from 1975 to 1985 while working at his clinic during the day.
He had served as a police guard to the Woodland Petroleum Tanks at night during the Indonesian Confrontation period, took part in police rounds at night in the Beach Road area and taught First aid and emergency resuscitation to Police recruits.
He received the Singapore Police Bicentennial 2020 Medallion on 1st March 2024 as recognition for his work in the Singapore Police.
Even as he grew older, Dr. Kee continued to work actively in his clinic, although he eventually reduced his consultation hours.
Beyond his medical career, Dr. Kee is also an author.
He started writing about medical conditions in 2007, using blogs and other online platforms to share his knowledge with a broader audience.
Over time, he published various books, many of which provide simple and accessible guides to different health conditions.
His works include "A Family Doctor's Tale," "My Personal Singapore History," and numerous medical guides, available through platforms like Amazon.
His books often combine his personal experiences as a family doctor with insights into Singapore's healthcare system and history.
Dr. Kee has written extensively on health topics, contributing to both medical literature and general knowledge resources.

Dr. Kenneth Kee has written numerous books, primarily focused on health education and personal experiences as a family doctor. Some of his notable titles include:
"A Family Doctor's Tale"
This book is a blend of Dr. Kee's personal experiences and his reflections on being a family doctor in Singapore. It's a great choice if you're looking for a narrative that combines both medical knowledge and human stories.
"Specialized Medical Conditions"
Books like **"Congestive Heart Failure: Diagnosis and Treatment"** focus on specific conditions, offering in-dept...
