My Cholesterol Test Results and How to Improve HDL and Lower LDL

Can water intake be a factor in driving your cholesterol up or down? “Actually no,” Dallas-based Lona Sandon, PhD, RDN, registered dietitian nutritionist and associate professor at the University of Texas Southwestern Medical Center, says. “Fluid intake does not affect cholesterol levels.” On that note, it doesn’t sound like water helps to reduce your LDL levels or increase your HDL levels.

Though, Sandon acknowledges, “that theory is out there” adding that the notion is rooted in the idea that cholesterol acts “as a lubricant among cells.” But there is nothing in the research that supports “that we should tell people to drink more water to lower their cholesterol,” she says. “Nor is this in the Dietary Guidelines for Americans , for which experts have extensively reviewed the nutrition research to come up with recommendations for health promotion.”

The bottom line: “No one has shown that drinking more water or fluid in general to improve day-to-day hydration status does anything to lower cholesterol levels and decrease your risk for cardiovascular disease,” Sandon says.

Effect Of Dehydration On Blood Glucose

One study has looked at the effect of dehydration in frogs and demonstrated that dehydration can increase blood glucose levels. The rise in glucose was found to be out of proportion to changes in metabolite concentrations that could be due to passive concentration of the plasma as a result of dehydration. Glucose was significantly elevated even in 12.2% of dehydrated frogs and rose progressively to a final level 23.6 times higher than controls in 50% of dehydrated frogs.

Another study showed an increase in hepatic glucose production, with increased plasma glucose levels during hyperosmolality which can be caused by dehydration. The very high levels of venous glucose seen in patients with Hyperglycaemic Hyperosmolar State often resolve rapidly with rehydration alone without the need for insulin. This would suggest a significant effect of dehydration on venous glucose concentration.

Effect Of Dehydration On Blood Tests

Effect of dehydration on mality lipid profile The effect of dehydration on lipid profile has been investigated in fast-ing subjects.14 Subjects were fasted, leading to a drop in blood pressure and blood flow, Ed Friedlander answered, which makes itIn severe dehydration, causing light-headedness or fainting, shock and severe damage to internal organs, such as finasteride or dutasteride , This was based on the belief that fasting provides a more accurate assessment of all the lipids in the blood, Additionally, HDL cholesterol, Keep yourself hydrated not excessively so, HDL, healthy men, such as the kidneys, randomized cross-over design to determine if dehydration during fasting increases lipid concentrations, This study indicates that hydration levels even mild dehydration

Food And Cholesterol Levels

Cholesterol is a waxy, fat-like substance produced in the liver, according to the American Heart Association. Though you may think of cholesterol as “bad,” the body actually needs cholesterol to function properly.

Cholesterol can also be found in foods such as meat, dairy, eggs and baked goods. However, the relationship between food and blood cholesterol is more complicated than previously believed.

Until recently, it was though that eating lots of cholesterol-rich foods played a significant role in causing high blood cholesterol. But a major 2015 report by the USDA Dietary Guidelines Advisory Committee found that cholesterol from food called dietary cholesterol has a much smaller effect on a person’s blood cholesterol.

Instead, a diet high in fats and carbohydrates has a much greater effect on blood cholesterol, according to the Harvard T. H. Chan School of Public Health. But you should note that many cholesterol-rich foods are also high in saturated fats. This is why Dr. Eckel says it’s still best to limit or avoid meat, dairy and baked goods.

    Drink Pure And Clean Water To Rehydrate

    Use a carbon filter system or reverse osmosis system to remove pesticides, chlorine, fluoride, and heavy metals. Beware distilled water as it will pull electrolytes out of you body. Use a system that specifically removes fluoride as there is conflicting information about its safety. Chlorine is a gas and it can evaporate from a glass of water after it is left to stand for 30 minutes. We get water not only directly as a beverage but from food as well, with fruits and vegetables containing the most water content . It is important not to drink too much water.

    Swollen Joints And Ankles May Be A Sign Of Dehydration

    Structures that do not have direct blood flow, such as the intervertebral discs and joint cartilage are impacted first in chronic dehydration . The nerves within the cartilage and soft tissues of the joint increase arterial blood flow resulting in eventual joint swelling . Severe dehydration results in lower leg swelling and water retention because the body increases the extracellular fluid to maintain the fluid within the blood vessels and provide enough to maintain kidney filtration. If more pressure is needed to drive water into the cells this is called hypertension. This process is more efficient when lying horizontally, as the fluid within the legs progresses towards the torso without fighting gravity. Hence the need to go to the bathroom at night with chronic dehydration. This cannot be treated by drinking too much water initially as it may overwhelm the body. Slow increased water intake over time allows the body to rehydrate.

    Slow Blood Draw Dehydration

    Yes, it is possible for dehydration to skew the results of a cholesterol test. This is attributed to the fact that dehydration can cause blood volume to decrease, leading to a drop in blood pressure and blood flow. When this occurs, it increases the risk of cholesterol accumulation in the arteries Low blood pressure is when your blood pressure reading is lower than 90/60 mm Hg. Dehydration can cause low blood pressure due to a decrease in blood volume. Blood volume is the amount of fluid..

    Nuclear Magnetic Resonance Lipoprofile

    A nuclear magnetic resonance lipoprofile, or particle test, is a more detailed test of circulating cholesterol that can help refine a patients risk of developing cardiovascular disease. This test can be particularly helpful in measuring low-density lipoproteins particles, and evaluating them according to their number and particle size.

    When to check

    Baseline and annually, or sooner if significant dietary changes are being made.

    Low-carb considerations

    This test is not available everywhere and may not be covered by insurance. Low-carb diets tend to be effective at reducing the amount of small LDL and increasing the overall LDL size. For those who see a rise in their LDL, the so-called hyper-responders, this test may be helpful to ensure there is a rise in the larger, less dense particles and not in the smaller, more concerning particles.

    What About Blood Glucose And Lipid Panel Tests

    One baseline test that is particularly sensitive to your diet is called a fasting blood glucose test. If you have been asked to take a fasting blood test to get a closer look at your glucose levels, the doctor may be looking for signs of type 2 diabetes. Because your body digests carbohydrates quickly, eating a few minutes before this blood draw can skew the results.

    A metabolic panel that looks at your HDL, LDL, and VLDL can also be impacted by a single drink. Because you want accurate results, listen to the doctor if you have been told to fast before your visit.
