Alpha Blockers And Keto: Friends Or Foes?

Alpha-blockers are a class of medications that treat high blood pressure and certain conditions affecting the circulatory system, prostate, and tumours. They work by slowing down specific types of cell activity in the nervous system. However, there is no evidence that alpha-blockers will keep you out of ketosis. In fact, there is no special need to use a carb blocker on a keto diet, as it is already a low-carb diet.

Alpha-receptors are a type of adrenergic receptor (sometimes identified by the Greek letter "α" for alpha). Adrenergic receptors are activated by adrenaline (also called epinephrine), which acts as a master key. When activated by adrenaline, alpha-receptors cause blood vessels to constrict and blood pressure to increase. They are located in the smooth muscle lining of blood vessels, the eyes, skin, and urinary tract, as well as the prostate.

Alpha-blockers are approved by the U.S. Food and Drug Administration (FDA) to treat high blood pressure, benign prostatic hyperplasia (BPH), and certain types of tumours called pheochromocytomas and paragangliomas. BPH is a condition where the prostate gland enlarges, making urination difficult. Alpha-blockers relax the prostate muscle, making urination easier. Pheochromocytomas and paragangliomas are tumours that can create excess adrenaline and norepinephrine, leading to symptoms such as headaches, sweating, and heart problems. Alpha-blockers prevent these excess neurotransmitters from causing an overdose-like effect.

In addition to their approved uses, alpha-blockers are also commonly prescribed off-label for conditions such as nightmares and sleep disruptions caused by post-traumatic stress disorder (PTSD), circulation issues, chronic prostatitis, and kidney stones.

While alpha-blockers offer advantages such as a medical alternative to surgery, they also come with certain risks and side effects. Selective alpha-1-blockers, for example, can cause low blood pressure (hypotension) and a significant drop in blood pressure when standing up (orthostatic hypotension). They may also lead to sexual dysfunction and priapism, a serious medical condition requiring immediate care. Non-selective alpha-blockers, which affect both A1 and A2 receptors, can result in a faster heartbeat (reflex tachycardia) and muscle tremors due to the activation of beta-receptors.

Alpha-blockers may interact with other medications, alcohol, citrus juices, or certain foods. They are generally not recommended for those with a history of orthostatic hypotension, cataract surgery, or breastfeeding. It is important to consult a healthcare provider before taking alpha-blockers to ensure they are suitable for your specific circumstances.

Alpha-blockers work by slowing down specific types of cell activity in the nervous system

Alpha-blockers are a class of medications that treat high blood pressure and certain conditions affecting the circulatory system, prostate, and certain types of tumours. They work by slowing down specific types of cell activity in the nervous system.

Alpha-blockers slow down cell activity by partially blocking the way some cells in the body receive instructions. They do this by blocking alpha-receptors, which are found on cells in specific areas or organs in the body. These receptors tell their cells when to squeeze, constrict or tighten. By blocking these receptors, those cells stay relaxed.

The human nervous system works by transmitting chemical and electrical signals throughout the body. This chemical communication works very similarly to a lock-and-key system. The chemical signals, also known as neurotransmitters, are the keys. They can travel through the bloodstream to various locations in the body. Receptors are the locks, allowing chemicals to attach and activate the cells.

Some of the receptors found throughout the body are called adrenergic receptors (or sometimes adrenoceptors). They are named this way because a chemical the body makes, adrenaline (also called epinephrine), acts as a master key and can activate all adrenergic receptors.

Adrenergic receptors, including alpha-receptors, come in multiple types and sub-types. Alpha-receptors come in two different subtypes, with some overlap but also controlling different functions.

Alpha-1 (A1) receptors are located in the smooth muscle, eyes, skin, urinary tract, and are also found in the nervous system, blood, pancreas, and fat cells.

Alpha-blockers have approval from the U.S. Food and Drug Administration to treat high blood pressure, benign prostatic hyperplasia (BPH), and pheochromocytoma.

Alpha-blockers are not the same as vitamins that help enhance insulin sensitivity or control the body's reaction to carbohydrates

Alpha-blockers are a class of medications that treat high blood pressure and certain conditions affecting the circulatory system, prostate, and specific types of tumours. They work by slowing down specific types of cell activity in the nervous system.

Vitamins that can help enhance insulin sensitivity include vitamin D, vitamin B, calcium, iron, and magnesium. Vitamin D, for example, helps manage blood sugar and improves insulin resistance in people with diabetes who are deficient in this vitamin. Vitamin B is essential for metabolising proteins and fats, and a deficiency in one type of vitamin B can affect other types, disrupting metabolism. Calcium supplementation has been linked to a small reduction in BMI, waist circumference, and body fat mass. Iron is vital for carrying oxygen in red blood cells, and magnesium is essential for energy production and metabolism.

In contrast, alpha-blockers work by partially blocking the way some cells in the body receive instructions. They do this by blocking alpha-receptors, which are found on cells in specific areas or organs of the body. Blocking these receptors keeps the cells relaxed, thereby lowering blood pressure.

While alpha-blockers can be an important medication for certain conditions, they do not have the same function as vitamins that help enhance insulin sensitivity or control the body's reaction to carbohydrates.

Carb blockers are supplements that help block the enzymes required to digest and process certain types of carbohydrates

Carb blockers come in two types: indirect or enzymatic inhibition, and direct inhibition. The former targets and stops the alpha-amylase enzyme, while the latter seeks out and binds to carbs in the digestive tract, preventing their absorption by the body. Most traditional carb blockers in supplement form operate via enzymatic inhibition.

Another type of enzymatic inhibitor is alpha-glucosidase inhibitors (AGIs). These prevent alpha-glucosidase from breaking down carbohydrates, delaying glucose absorption and helping to stabilise blood sugar levels. AGIs are prescription medications typically used to treat high blood sugar in type 2 diabetics. They are not typically available as supplements, but their effects can be experienced through natural supplements containing Salacia plant extract.

It is important to note that carb blockers only work with complex carbohydrates. They are ineffective against simple carbs and sugars, so they are not a shortcut for indulging in sweet treats while on a ketogenic diet.

Carb blockers have been linked to several benefits, including weight loss, blood sugar control, and appetite suppression. By blocking the digestion of complex carbs, they can help prevent spikes in blood sugar and make it easier to control weight. Additionally, they may influence hormones related to hunger and fullness and slow down stomach emptying, reducing cravings.

While carb blockers can be a useful tool, it is essential to remember that they are not a substitute for a healthy lifestyle. A well-balanced diet and regular exercise are still necessary to achieve lasting results.

Carb blockers are not the same as supplements that improve insulin sensitivity

Carb blockers, also known as starch blockers, are supplements that help block the enzymes required to digest and process certain types of carbohydrates. They are scientifically known as amylase inhibitors, which means that they block the enzyme alpha-amylase, produced within your saliva to help digest carbohydrates. Carb blockers are designed to help your body process moderate amounts of carbs without taking it out of ketosis.

On the other hand, supplements that improve insulin sensitivity work to improve blood sugar control and insulin sensitivity. These supplements are not designed to keep carbs out of the bloodstream entirely, as is the case with carb blockers. Instead, they help to reduce blood sugar spikes in response to eating carbs and improve insulin sensitivity.

Carb blockers work by inhibiting the production of enzymes that break down carbs, whereas supplements that improve insulin sensitivity work by influencing hormones that control blood sugar and insulin levels. Carb blockers are designed to prevent the absorption of complex carbohydrates, while supplements that improve insulin sensitivity can help regulate hormones that affect hunger and fullness.

While carb blockers can be effective at blocking carb digestion, they do not prevent the absorption of simple sugars such as table sugar, fruit juice, sweetened beverages, and corn syrup. Additionally, the effectiveness of carb blockers may be limited, as they only prevent a portion of the carbs you eat from being digested.

Supplements that improve insulin sensitivity, on the other hand, have been shown to have a more significant impact on blood sugar control and insulin sensitivity. These supplements can help reduce blood sugar spikes and improve insulin sensitivity, which is especially beneficial for individuals with type 2 diabetes.

In summary, carb blockers are designed to block the digestion of carbohydrates, while supplements that improve insulin sensitivity work to enhance blood sugar control and insulin sensitivity. Carb blockers prevent carbs from entering the bloodstream, whereas supplements that improve insulin sensitivity focus on reducing blood sugar spikes and improving the body's ability to utilise insulin.
