Why Thiazide Diuretics Are Used In Diabetes Insipidus

Why are thiazides effective against diabetic insipidus? In reality, the idea that is most frequently accepted is that the antidiuretic effect of thiazides is related to an increase in renal sodium excretion (1,2,6?? ). Reduced GFR and higher proximal tubular sodium and water reabsorption result from sodium loss in the kidney.

Why do diabetics take thiazide diuretics? The cardiovascular event reduction benefits of thiazide diuretics exceed the risk of deteriorating glucose control in type 2 diabetes and new-onset diabetes in non-diabetic individuals. Thiazides continue to serve a crucial role in the treatment of type 2 diabetes and hypertension.

Helpful three-part strategy for a low-fat, plant-based, whole-food diet that treats and avoids Prediabetes/Diabetes II (also cures/prevents high blood pressure and high cholesterol). Very comprehensive description of insulin resistance and its treatment.

I’m pleased the book gave solid facts and information on why a low-carb, high-fat diet is not sustainable.

Diet works if you adhere to it, as simple as that. It is simple to sustain this diet long-term.

Can thiazide diuretics induce diabetic insipidus? Utilization of thiazides in the treatment of nephrogenic diabetic insipidus. Substance abuse is the leading cause of NDI [3]. This disorder is characterized by the kidney’s insensitivity to the effect of vasopressin.

Why Thiazide Diuretics Are Used In Diabetes Insipidus – RELATED QUESTIONS

How is the diuretic drug hydrochlorothiazide used to treat nephrogenic diabetic insipidus?

Hydrochlorothiazide (Microzide) In the absence of ADH, hydrochlorothiazide is a thiazide diuretic that lowers urine volume. It may produce moderate volume depletion and proximal salt and water retention, hence decreasing blood flow to the ADH-sensitive distal nephron. It contributes to the effects of other agents.

What is the recommended treatment for diabetic insipidus?

Central diabetes insipidus. Typically, this kind is treated with desmopressin, a synthetic hormone (DDAVP, Nocdurna). This medicine reduces urination by replacing the anti-diuretic hormone (ADH). Desmopressin is available in tablet, nasal spray, and injectable form.

What is the mechanism through which thiazide diuretics function?

The mechanism of action of thiazide diuretics is to inhibit sodium reabsorption and, therefore, fluid reabsorption; this directly reduces circulating sodium levels.

What is the best diuretic for diabetics?

We conclude that Indapamide is safe and effective for decreasing blood pressure and leads to improved glucose and lipid management in diabetic and dyslipidemic individuals compared to conventional diuretics.

Which diuretic is preferable for diabetic patients?

As monotherapy or as part of a combination regimen, thiazide diuretics are effective in the treatment of hypertension in diabetic individuals.

What is thiazide diuretics’ major target?

The sodium-chloride symporter (SLC12A3, NCC) is the principal target of hydrochlorothiazide (and other thiazide/thiazide-like diuretics) on the apical membrane of the renal distal tubule. Hydrochlorothiazide is delivered from the blood to its site of action through the organic acid secretory route of the proximal tubule of the kidney.

How does thiazide inhibit urine production?

Thiazide diuretics lower total body sodium via an initial natriuresis, leading in a reduction in extracellular fluid volume and glomerular filtration rate. These alterations result in an increase in fluid reabsorption in the proximal renal tubule and a decrease in urine output.

Why are thiazides preferable over furosemide in the treatment of hypertension?

Thiazide-type diuretics are effective first-line medicines for the treatment of hypertension since it has been shown that they decrease cardiovascular mortality and morbidity in systolic and diastolic types of hypertension at a reasonable cost.

How does vasopressin act in diabetic insipidus?

Central diabetes insipidus The pituitary gland secretes vasopressin into the circulation when the quantity of fluids in the body becomes insufficient. The hormone instructs the kidneys to preserve fluids by reabsorbing fluid from the urine and returning it to the circulation.

What is the mechanism of hydrochlorothiazide’s action?

Method of Operation The distal convoluted tubule sodium chloride transport is inhibited by hydrochlorothiazide. The kidney then excretes more salt with the associated fluid. After an oral dosage, the onset of pharmacological effects occurs within two hours, peaks within four hours, and lasts between six and twelve hours.

Is vasopressin a treatment for diabetic insipidus?

The treatment of both central and gestational diabetes insipidus. The first-line therapy for central diabetic insipidus is desmopressin. This medicine functions as an antidiuretic hormone (ADH, or vasopressin). Desmopressin may be administered as an injection, a tablet, or a nasal spray.
The pathogenesis of diabetic insipidus is as follows:
An imbalance in the functioning or levels of antidiuretic hormone (ADH), also known as vasopressin, causes diabetes insipidus. ADH, which is produced in the hypothalamus and stored in the pituitary gland, serves to control the body’s fluid balance.

Why is the sodium level elevated in diabetic insipidus?

In all cases of hypertonic dehydration, serum sodium and osmolality will be high. The skin, lungs, and kidneys all contribute to excessive water loss. Fever, increased respiration, and diabetes insipidus are the causes. Most cases of hypotonic dehydration are caused by diuretics, which result in more salt loss than water loss.

How is hyponatremia managed in diabetic insipidus?

Fluid replacement The majority of people with diabetes insipidus (DI) can restore their urine losses with sufficient fluid intake. When oral intake is insufficient and hypernatremia is present, replenish losses with dextrose and water or a hypo-osmolar intravenous (IV) fluid relative to the patient’s serum.

How are vasopressin and desmopressin dissimilar?

Desmopressin, a synthetic version of the human hormone vasopressin, reduces the volume of urine produced. It may be taken nasally, intravenously, orally, or sublingually. Desmopressin’s primary applications include the treatment of bedwetting, midnight urination, coagulation abnormalities, and diabetes insipidus.

How do thiazide diuretics cause urine to increase?

Method of Operation Thiazides enhance urine production by blocking the NaCl cotransporter on the luminal membrane of the first segment of the distal convoluted tubule, also known as the cortical diluting segment (Fig.

What is the function of thiazide diuretics?

Thiazide diuretics are indicated as one of the initial medications to treat hypertension. If diuretics are insufficient to decrease your blood pressure, your doctor may prescribe additional blood pressure drugs.

Do diuretics suppress ADH?

The administration of a loop diuretic inhibits the buildup of sodium chloride in the medulla, hence interfering with this process. Thus, whereas the loop diuretic may enhance ADH levels by generating volume depletion, the weakening of the medullary gradient reduces the response to ADH [9].

Diabetics: Are thiazide diuretics safe?

The effects on blood glucose have sparked particular concern because data from clinical trials indicate that thiazide-based treatment, when continued for years, is associated with an increased incidence of type 2 diabetes compared to placebo or drugs such as renin–angiotensin system blockers or calcium-…

Why are diuretics necessary for diabetics?

According to the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial, diuretics (water pills) are more effective than newer and more expensive drugs in the treatment of high blood pressure and prevention of some kinds of heart disease in patients with type 2 diabetes (ALLHAT).

Why are thiazides responsible for hyperglycemia?

In addition, it is hypothesized that thiazide diuretics down-regulate peroxisome proliferator-activated receptor gamma, reducing insulin release, as well as stimulating the reninangiotensin-aldosterone pathway, resulting in higher aldosterone levels and hyperglycemia.

Why is Lasix not recommended for diabetes?

If you have diabetes, Lasix may impact your glucose levels. Regularly test your urine or blood and report any significant changes to your doctor. Your skin may become more sensitive to sunlight if you are using Lasix.

This is the finest diabetic book that I have ever read. The excellent ones all recommend a high-carbohydrate, low-fat, plant-based diet, but this one explains why we should follow this diet. I have been a whole-food, plant-based eater for around five years, but I ate too many nuts, nut butters, and seeds despite the fact that they are entire foods.

As soon as I read the explanation in this book, I saw why too much fat was harmful. My insulin consumption went from 30 units per day to 12 units per day, and it seems to be moving even lower, and my blood sugar management has improved to the point that it is almost predictable, while on a high-fat diet, my blood sugar was like a random walk.

I adore this book! BTW, except when I’m fasting, I’m never hungry. Intermittent fasting is not required, but it does help you lose weight and activate your cellular defenses. Eating according to the advice in this book will help mend your metabolic disease, and you will lose weight. Good luck!!!!
