Beta blockers- what are they?-by Dr Harold Gunatillake Website: www.Doctorharold.com Transcript: Beta blockers are used to treat high blood pressure. In my recent previous videos, I have discussed other specific drug groups that lower your blood pressure- such as ACE inhibitors, ARBs, and Calcium-channel blockers. Today we discuss how betablockers lower your blood pressure, and other uses. Beta blockers are also known as beta-adrenergic blocking agents, are medications used to slow down your heart rate, with less force to lower your blood pressure. ...

Angiotensin receptor blockers (ARB’s) – how do they lower your high blood pressure-by Dr Harold Gunatillake Transcript: What are ARBs? They block the action of angiotensin 11 resulting in lowering of blood pressure. Angiotensin 11 a vasoconstrictor i.e., narrows blood vessels causing increase of blood pressure. Further, angiotensin 11 is a stimulus for salt and water retention in the body, which further increases blood pressure. Angiotensin 11 is derived from an inactive Angiotensin 1 produced from Angiotensinogen a protein made in your liver. ARBs reduce or blocks the action of this hormone angiotensin 11, thereby causing dilatation of blood vessels resulting in lowering of blood pressure. ARBs blocking the action of Angiotensin 11, lowers the blood pressure and prevent damage to the heart and kidneys caused by high blood pressure. So, those who take ARBs should realize that they are also effective in heart and kidney health, in addition to ...

Mechanism of blood pressure control with ACE inhibitors-by Dr Harold Gunatillake Website:www.Doctorharold.com Transcript: Your body has a system to keep your blood vessels narrowed, increase salt retention and water- to maintain the blood pressure in case of emergency situations such as traumatic bleeding, and at other times. This system is called the Renin-Angiotensin-Aldosterone System or RAAS. When the blood pressure increases with age due to over-reaction of this system, there are counter-acting drugs to minimize this situation. We are discussing today about Angiotensin converting enzyme inhibitors, or ACE inhibitor drugs used to maintain a normal range blood pressure. ...

Calcium channel blockers-by Dr Harold Gunatillake Website: www.Doctorharold.com Transcript: Do you know what calcium channel blockers are? Most of you may be on a calcium channel blocker, prescribed by your family physician, without your knowing, for High Blood Pressure (essential hypertension). They are also called calcium antagonists, given for the treatment of a variety of conditions, such as high blood pressure, migraine and Raynaud’s disease (peripheral arterial spasm). Calcium is required by the heart muscles and other blood vessels for efficient contraction movement. So blocking such a mechanism or inhibiting transport of calcium into cells will lower the blood pressure and widen blood vessels by affecting the muscle cells in the arterial walls, especially those of the coronary arteries. ...

What is the significance of doing a fasting blood sugar level when you are a diabetic?-Dr Harold Gunatillake Do peruse my website:www.Doctorharold.com Transcript: Normally in a non-diabetic the fasting blood sugar level reading in the morning after an overnight fast is 99 mg/dL or lower is normal. Or 3.9 to 5.5 mmol/L 100 to 125 mg/dL or 5.5 mmol/L to 7 mmols/L indicates you have prediabetes and 126 mg/dL or higher indicates you have diabetes. Most people having diabetes complain that even with strict control with diet and medication, the morning fasting level seems to be high and worried about the readings. Fasting blood sugar is more diagnostic to check whether you have excess blood sugar. That would be the routine test your doctor will request on your annual blood check, sometimes with the HbA1C test. ...

Disruptive outbreaks expected after the borders are open.- By Dr Harold Gunatillake   A third booster could be Novavax in Australia. Do not wait for your so-called favorite vaccine, as unvaccinated people are far more likely to die of COVID-19 It seems that highly transmissible Covid-19 variants – copies of Delta, are circulating in many overseas countries, and the fears that, when Australian borders are open soon, an influx of people returning or visiting Australia may result in an unexpected outbreak, is a possibility. Complacence after 80% of people over 16 years fully vaccinated is questionable as incidence of breakthrough outbreaks are on the rise in other countries. We are fortunate in Australia that the breakthrough COVID-19 infections have been slightly more than five hundred. It has been observed that the AstraZeneca COVID vaccine has the same rate of effectiveness in keeping people alive and out of hospital as much ...

Know your Extracellular fluid and its importance-By Dr Harold Gunatillake Transcript: The regulation of body fluids balance is the key to good health and wellbeing. The body is composed of a skeletal framework, muscles, organs all composed of cells with metabolic activities in them for healthy living. There is also a component referred to as the extracellular fluid that fills in the spaces in between the cellular component. In short this is the body fluid that is outside the cells. It is in your blood, in lymph, in body cavities lined with an inner lining such as the ventricles in brain, spinal cord and this fluid referred to as the cerebrospinal fluid. This fluid helps protect the brain and spinal cord by acting like cushion against sudden impact or injury and removes waste products from the brain and helps your central nervous system work properly. ...
