High cholesterol and lactation-How Breastfeeding Benefits Mothers' Health - Scientific American

This sheet talks about having high cholesterol during pregnancy and while breastfeedings. This information should not take the place of medical care and advice from your healthcare provider. Cholesterol is a substance in the body that is needed for your body to work properly. Too much cholesterol, however, increases the chance for heart disease, which can lead to heart attacks and strokes. A blood test can tell if you have too much cholesterol.

Log in. I certainly did not have to stop BFing. Breastfeeding babies experience high cholesterol levels while nursing and it is believed cholesterol in breast milk plays an important role in health well beyond the nursing years. The concentrations of both Asian intro page and triglycerides remain significantly higher in bottle-feeding than in breast-feeding mothers. Excess LDL can build up lactatjon artery walls, blocking blood flow to the heart and brain. Getting Pregnant. By Marie Karns qnd. Risk increases after menopause Women should get their first lipoprotein profile at age 20, then once every five years if they have no additional lsctation for heart disease. May in Breastfeeding. Claire Blocker, of Charlotte, N. Yet, at age 47 she suffered High cholesterol and lactation stroke, followed by a heart attack and quadruple High cholesterol and lactation at Get weekly updates on baby and your body. Therefore, the present study investigated changes in lipids and lipoproteins throughout the pregnancy and puerperium. It is interesting that cholesterol is normally higher during pregnancy and lactation. I'm not sure what to do, but the ladtation wasn't very helpful.

Why your cholesterol levels are naturally higher in pregnancy and breastfeeding, and why you should steer clear of cholesterol-blocking food products.

  • So I went to the doctor earlier this month and they checked my cholesterol.
  • Excessive accumulation of one or more of the major lipids in plasma can produce a marked increase in the risk of coronary heart diseases and other vascular complications.

Origins of hyperlipidemia and cholestasis that occur during pregnancy were investigated by examining expression of key elements related to plasma and hepatic cholesterol metabolism during pregnancy, lactation, and post-lactation in the rat model. In later stages of lactation most hepatic elements returned to near control levels. Plasma cholesterol levels were higher than control at birth and during lactation with increase in LDL-size particles. By 24 h post-lactation, plasma triglycerides were 3.

Very large lipoproteins were present while LDL-size particles were now absent. Most elements were normalized 3 weeks after weaning except for LRP and low density lipoprotein receptors which were elevated. These studies provide an integrated picture of expression of key elements of hepatic and plasma cholesterol metabolism during pregnancy and lactation and advance understanding of hyperlipidemia and cholestasis during these states.

Lear, T. Forte, W. Ko, M. Massimi, and S. Effect of pregnancy and lactation on lipoprotein and cholesterol metabolism in the rat. Lipid Res.

Hyperlipidemia of pregnancy in humans was first described over years ago 1 and has been studied extensively since 2 — 7. It occurs in virtually all pregnant women and resolves in most in the first months after delivery. A positive association of this hyperlipidemia with later development of cardiovascular disease has been suggested 8 ; and a supraphysiologic increase has been proposed as a marker for development of non-pregnancy-associated hyperlipidemia in later life 9.

A low density lipoprotein LDL pattern B profile, i. Cholesterol and lipoprotein concentrations tend to normalize in the year after pregnancy 12 , Epidemiological studies of the relationship s between pregnancy and later risk for cardiovascular disease have shown mixed results 14 and references therein.

An increased propensity for cholesterol gallstone formation in human pregnancy also is well known 15 , 16 and is a predictor for development of cholesterol gallstone disease in later life Intrahepatic cholestasis of pregnancy also is a well-described entity in humans which generally also resolves after delivery.

It was first noted over years ago 18 and described in detail in It is associated with higher than normal serum lipid levels during pregnancy 20 , 21 , suggesting a link between cholestasis and hyperlipidemia. In one study, serum cholyl-glycine levels doubled during pregnancy in all individuals studied 22 suggesting that some degree of cholestasis is normal in all pregnancies.

Although the incidence of clinically apparent cholestasis is less than 0. Thus, in humans, pregnancy induces changes in cholesterol metabolism that result in phenotypes associated with the development of pathologies such as atherosclerosis and cholesterol gallstone disease in the general population. However, the origins of these changes remain obscure.

The liver plays a central role in the maintenance of whole body cholesterol homeostasis by integrating regulation of a group of hepatic enzymes, receptors, and other proteins important for cholesterol, lipoprotein, and biliary metabolism. The interactions and regulation of these pathways to maintain cholesterol homeostasis during pregnancy and lactation have not been studied systematically or in an integrated fashion.

We hypothesized that hepatic regulatory elements and their integration for maintainence of cholesterol homeostasis undergo major changes during pregnancy and lactation to ensure that cholesterol homeostasis is maintained optimally for both the mother and the developing offspring and further, that these changes are related to the etiology ies of hyperlipidemia and cholestasis of pregnancy. The rat was chosen as a model for these studies because, like the human but unlike a number of other species 24 , 25 , the rat develops hyperlipidemia during pregnancy 26 — 28 and, like humans, the rat also develops cholestasis 29 as does the hamster Thus, the rat is a suitable model for studying the origins of changes in both lipoprotein and biliary metabolism that are observed during pregnancy and lactation in humans.

To gain further and more detailed insight into the regulation of cholesterol, lipoprotein, and biliary metabolism during pregnancy and lactation, the hepatic expression of a number of enzymes, receptors, and proteins important in hepatic cholesterol metabolism was investigated.

A scheme showing key elements involved in the regulation of hepatic cholesterol, lipoprotein and biliary metabolism is shown in Fig. Adult female — g and timed pregnant — g Sprague-Dawley rats Bantin and Kingman, Newark, CA, or Simonsen, Gilroy, CA were housed under reverse illumination lights on 3 pm ; lights off 3 am for at least 1 week prior to use. They were allowed free access to food Purina Rat Chow and water at all times. In pregnant animals the fetuses were removed prior to removal of blood samples followed by removal of the liver.

All liver and blood samples were collected at or about am D6 , except for two immediate post-delivery samples 2 h which were collected at pm and pm. All lactating dams had 9—14 suckling pups. Suckling pups were removed from lactating dams at 21 days of age.

Homogenates, microsomal membranes, and cytosolic fractions were prepared as previously described A sinusoidal plasma membrane-enriched fraction also was prepared as previously described All preparations were from freshly isolated livers. Plasma and serum cholesterol and triglyceride concentrations were determined as described previously Rat plasma collected as above was adjusted to density 1.

Scheme for hepatic cholesterol, lipoprotein, and biliary metabolism. All were assayed in the linear ranges of detection as determined in preliminary experiments. The values are expressed in units defined relative to a standard pooled rat plasma set as , an ali-quot of which was run simultaneously on each gel. Enzyme activities were measured in freshly prepared microsomes or cytosol.

Low density lipoprotein LDL receptor protein content was estimated in membrane fractions enriched in sinusoidal plasma membranes by SDS gel electrophoresis under reducing conditions followed by transfer and immunoblotting as described previously 32 using an LDL receptor-specific antiserum provided by Dr. Scavenger recepter, Class B SR-B1 content was estimated by immunoblotting as described above using whole liver homogenates prepared as described above and an SR-B1 specific antiserum provided by Dr.

Protein was estimated by the biuret method 37 using bovine serum albumin as reference standard. As reported previously by others 26 — 28 , pregnant rats at term were hypercholesterolemic Fig. This condition lasted throughout the lactation period. In contrast, triglyceride concentrations were in the normal range in near term rats. This may reflect the time of day at which they were killed D6 ; other studies used basal L6 rats.

The day after weaning of the pups, cholesterol concentrations were variably elevated and remained significantly elevated thereafter until 21 days post weaning 42 days postpartum when they were similar to controls Fig. Plasma triglyceride concentrations were elevated 4.

Control rat VLDL were of relatively small size with a mean particle diameter of 36—37 nm. The control LDL were small in diameter 23 nm. However, by the mid and late lactation period days 12—19, Fig.

The 1-day post-lactation stage was distinguished by the absence of LDL particles and the presence of a substantial quantity of very large lipoproteins which remained at the top of the gel Fig.

Plasma cholesterol and triglyceride concentrations during pregnancy, lactation, and post-lactation. Pups were delivered at day 0. Negative days refer to days of pregnancy prior to birth.

Pups were weaned at day Panel A, cholesterol; panel B, triglycerides. During lactation, rather than becoming larger, the particles were skewed towards smaller size. At 3 days, an asymmetrical peak at With increasing time of lactation the HDL particles became even smaller 9.

After the pups were weaned, the HDL pattern began to revert to larger-sized particles and the pattern was normalized by 21 days post-lactation compare Fig. Lipoprotein size distribution patterns in plasma from lactating and postlactating rats determined by non-denaturing gradient gel electrophoresis. Gels were stained with Coomassie R and scanned for profiles.

Panel A: 3 days lactation; 12 days lactation; 19 days lactation; control. Panel B: 1 day after removal of pups; 7 days after cessation of lactation; and 21 days after cessation of lactation. Numbers over the peaks correspond to particle diameters in nm. Representative profiles are shown. This corresponds to a time when the pups may begin to ingest solid food as well as milk. After first suckling, apoB was at control levels and remained similar to this until day 6 when levels had begun to increase.

By days 12 and 17 of lactation, apoB had increased significantly to about 2. At this time point, serum apoB may be enriched with that from the intestine because the intestine has hypertrophied 2-fold by the midsuckling period 38 — 40 potentially leading to increased secretion of lipoproteins. The lack of VLDL-size particles and presence of large LDL-size particles at this time period suggest that most of the apoB may be in small remnants. This reflects the presence of the very large lipoproteins found at this time period see above which likely reflects an overshoot phenomenon due to coupling of normal or enhanced intestinal chylomicron production with a decrease in mammary gland production of remnants.

By 7 days post-lactation, apoB levels were similar to those in controls. Because most of the plasma apoE is thought to be of liver origin, this suggests that liver production has been down-regulated, perhaps to ensure longer residence of lipoproteins in the circulation in order to fulfill placental and mammary gland requirements for lipids in late pregnancy and for mammary gland milk production during lactation. Alternatively, apoE levels are low because it was removed very rapidly from the circulation, in particular, by the liver in late pregnancy and by other organs during lactation.

However, by 7 days after cessation of lactation, levels of apoE had begun to increase and by 21 days post-lactation, they were statistically similar to those of controls. By 21 days post-lactation, apoA-IV had returned to control levels. At day 12 of lactation, values were highly variable and not statistically significantly different from control. Plasma apolipoprotein patterns for pregnant, lactating, and post-lactating rats. The plasmas described in Fig.

Late pregnancy and post-lactation apoC-III values tended to be in the control range. HMG-CoA reductase. This is a rate-limiting enzyme for mevalonate and cholesterol synthesis. This reflects data on cholesterol synthesis 41 , 42 and HMG-CoA reductase 43 reported by others and underlines the fact that the fetus makes most of its own cholesterol rather than deriving it from maternal lipoproteins 42 , It did not return to control values until 21 days post-lactation, suggesting a decreased requirement for de novo synthesized sterols in the late lactation and post lactation periods.

Biliary metabolism in rats is known to be altered in pregnancy and lactation 29 , 46 — This suggests that the cholestasis of pregnancy had been reversed significantly. The data taken together suggest that some level of intrahepatic cholestasis may have been present during much of the lactation period or alternatively, an increased enterohepatic circulation is present.

Discuss: Discussion comments. Overweight and obese adults, and those who have a family history of high cholesterol or heart disease, are at especially high risk. The concentrations of both cholesterol and triglycerides remain significantly higher in bottle-feeding than in breast-feeding mothers. While synthetic infant formulas are beginning to include fatty acids, the absorption of these additives is less effective than in breast milk. While the exact benefits of breastfeeding and cholesterol are still being studied, it is evident breastfeeding does provide many advantages to babies and mothers and is proven to reduce the risk for many diseases and conditions beyond high cholesterol.
