Causes and consequences of elevated sugar levels in urine during pregnancy

The body experiences numerous changes during pregnancy, some of which may have unanticipated effects on health. Elevated urine sugar levels, which can occasionally be seen in pregnant women, are one of the conditions that frequently causes concern. Even though it can be concerning, the first step in resolving this issue is comprehending the reasons for the rise.

Elevated urine glucose levels during pregnancy are frequently associated with altered glucose metabolism. On the other hand, it may also indicate a possible problem such as gestational diabetes, which needs to be closely watched over and managed to protect the health of both mother and child.

It’s critical to understand the possible outcomes of ignoring this condition. Although high blood sugar levels can have an impact on pregnancy, most women are able to handle the situation well with the right support and advice from medical professionals. To ensure a healthy pregnancy journey, it will be helpful to understand the causes and effects.

Norms and deviations

The human body needs glucose to function; it gives it the energy it needs. During pregnancy, a woman needs glucose twice as much. Pregnant women’s blood sugar levels may be slightly elevated, within the upper limit of normal, because glucose is transferred from the mother’s blood to the fetus through the uteroplacental bloodstream along with vitamins, minerals, and oxygen. Since the renal tubules absorb all glucose, a healthy person should never have any sugar in their urine.

Additionally, there is no need to become alarmed if there is a trace amount of glucose in the excreted fluid—a general urine test frequently finds none at all.

Urine sugar levels rise briefly in about 10% of expectant mothers; these are isolated, one-time events that shouldn’t raise any red flags. Because of the peculiarities of the childbearing period, the standard is thought to be an indicator of no more than 1.7 mmol/liter. It is considered acceptable to have no more than 0.2% of sugar in the urine during the second and third trimesters of pregnancy.

Diagnostics

A woman gives urine for analysis at each visit to the doctor, and therefore an increase in sugar in it or the detection of traces of glucose will certainly become obvious. In this case, the attending physician will prescribe an additional examination, the task of which is to establish whether the increase in glucose levels is physiological and harmless or is it a sign of the development of a disease. The woman will have to take an unscheduled blood test for sugar, a blood test for hormones (in particular, for the content of thyroid hormone, to establish the characteristics of insulin production), as well as a clinical blood test, in which they will look for glycated hemoglobin.

The following table illustrates how the quantity of glucose in secondary urine and blood sugar levels are directly correlated:

A glucose tolerance test is recommended for women whose repeated tests show elevated blood sugar levels. A test for glucose tolerance is run on an empty stomach. A woman is given a glass of water diluted glucose, and two hours later the outcome is evaluated. After this point, diabetes will be suspected if the pregnant woman’s capillary blood sugar level is greater than 6.8 mmol/liter.

The expectant mother will be referred for consultation to a nephrologist and endocrinologist to rule out kidney disease and some important glands if the glucose tolerance test is successful.

Glycosuria, or elevated sugar levels in the urine during pregnancy, can be brought on by changes in hormones or the body’s incapacity to properly process glucose. While persistently high levels may be a sign of gestational diabetes, which can cause complications if left untreated for both the mother and the unborn child, they can also be a normal part of pregnancy. To guarantee a healthy pregnancy and lower risks like preterm birth, high birth weight, or diabetes in the future for both the mother and the child, it is imperative to monitor and treat this issue as soon as possible.

Reasons for increased sugar

There are two possible explanations for the expectant mother’s elevated urine sugar content: pathological and totally natural. Let’s examine both situations.

Physiological reasons

The body of the expectant mother "cares" not only about its own energy well-being (and a pregnant woman requires much more energy!), but also about providing the baby with glucose, which requires energy for growth and the formation of organs and systems. And therefore, the mother"s body switches on the glucose accumulation mode "for a rainy day". That is why the sugar content may be elevated. The appearance of sugar or its traces in the urine can be affected by the woman"s diet and lifestyle. If she gets little rest, is very nervous, eats a lot of sweets, then it is not surprising that a urine test will show a certain amount of glucose in the excreted fluid.

Pathological causes

The presence of sugar in the urine may indicate renal issues. The secondary urine is sent for analysis if the renal tubules are unable to handle the "utilization" of extra glucose. Diabetes may be indicated by high blood and urine sugar levels. For a long time, many women are unaware that they have issues with their body’s ability to absorb glucose; it is only during pregnancy, when the demands placed on their bodies increase tenfold, that this becomes apparent. Gestational diabetes is an additional issue. It appears during pregnancy and disappears a few months after delivery in 99% of cases.

The issue could be caused by thyroid dysfunction or by the pancreas, which is responsible for producing insulin, not working properly.

Symptoms

It’s possible for a woman to feel normal. Even so, most expectant mothers usually credit any symptoms they experience to their condition because malaise is a common occurrence in expectant mothers, particularly in the early and late stages of the condition. The woman should "listen" to her condition more closely if sugar is found in her urine.

• feeling of being "broken" for no apparent reason, chronic fatigue, decreased overall tone;
• increased sleepiness, even if the woman sleeps enough time and has no problems with sleep;
• instability of body weight, which is manifested by either a decrease or an increase in weight for no apparent reason;
• appetite that is difficult to control;
• constant feeling of dry mouth, thirst that makes the expectant mother drink a large amount of liquid;
• frequent urination.

If such symptoms are found, the expectant mother should definitely report them to the doctor because diabetes, in any form, can have a serious negative impact on the mother’s health as well as the state and development of the fetus.

Possible consequences

In the absence of medical supervision and treatment, elevated blood and urine sugar levels can seriously complicate the lives of the expectant mother and her unborn child if they are not a one-time, transient event.

First off, a pregnant woman’s chance of developing gestosis increases tenfold. This illness, which is linked to edema and hypertension, directly jeopardizes the viability of a pregnancy and can lead to major birth complications.

One risk factor for the child’s development is maternal diabetes. It is well known that a pregnant woman with high blood sugar can have irreversible, comprehensive, and frequently fatal fetal abnormalities and defects.

Elevated blood sugar levels in the mother can lead to problems with the child’s respiratory system and function, as well as serve as a good foundation for the development of neurological disorders in the infant.

Rarely, a very dangerous side effect called congenital diabetes in newborns may develop. These infants are essentially destined to use synthetic drugs for the rest of their lives due to their severe lack of insulin, as their own pancreas is either underdeveloped, nonexistent, or not developed enough to function.

Treatment

A pregnant patient may receive care at home or in a hospital. The precise level of sugar in the urine will determine the doctor’s decision; if the value is high or dangerous, the pregnant woman may need to be hospitalized.

Initially, the pregnant woman’s diet is modified. Rich dough, chocolate, baked goods, and fruit juices are all off limits for her diet. Suggested foods include lean meats, seafood, fresh veggies, legumes, greens, and homemade fruit compotes and drinks without added sugar. Eat small portions frequently and in fractions of a meal.

At least five to six meals a day are required of you. Overeating is regarded as just as dangerous as starvation because it can cause a sharp drop in blood pressure, which increases the risk of fetal death when consumed too soon or skipped altogether.

The obstetrician-gynecologist will keep a close eye on the expectant mother’s weight. The body will be under too much strain if it gains more than one kilogram per week. The expectant mother will also need to see an endocrinologist at the same time and frequently have her blood and urine sugar levels checked.

In most cases, gestational diabetes is a transient condition that can be managed without medication; instead, doctors believe that leading a healthy lifestyle and strictly adhering to the recommended diet are sufficient. For this reason, they do not think it is appropriate to prescribe medications for the condition.

You will be able to control your weight if you avoid sitting in front of the TV on the couch during treatment and instead take long walks in the fresh air and engage in reasonable physical activity.

The amount of glucose the body uses is reduced when there is no physical activity. The likelihood that glucose will stay "in reserve" is low if they are present, as the energy requirements rise.

It doesn’t take as long to treat gestational diabetes as it might initially appear. In a few weeks, the blood and urine sugar levels should return to normal if you follow all the instructions. This does not imply that you can unwind and resume eating cakes and chocolates after this.

To prevent a recurrent rise in blood sugar levels during the tests, you will need to exercise self-control all the way up to birth.

During pregnancy, elevated urine sugar levels may indicate gestational diabetes or other health issues. To keep the mother and the child safe, it’s critical to keep a close eye on these levels.

High blood sugar levels can cause issues like larger-than-average babies, premature delivery, or even health issues for the newborn if they are not treated. A healthcare provider’s routine examinations can aid in the effective management of the condition.

Most women are able to control their blood sugar levels and have a healthy pregnancy by eating a balanced diet, exercising regularly, and taking prescribed medications when needed.
