Should Women Wear Seatbelts During Pregnancy

Seatbelts should absolutely be worn during pregnancy. Trauma to the mother is more devastating to the child than any potential entrapment of the pregnant abdomen in the seatbelt. The seatbelt should be placed low, across the hip bones and under the pregnant abdomen. The shoulder strap should be placed to the side of the abdomen, between the breasts, and over the midportion of the clavicle. No information indicates that air bags are unsafe during pregnancy. Pregnant women should try to keep their abdomen 10 inches from the airbag.

Healthy women are generally recommended to get 150 minutes of moderate-intensity exercise such as walking, jogging, or swimming each week.

Do Older Fathers Have An Increased Risk Of Fathering Children With Birth Defects

No medical information exists to support the hypothesis that increased paternal age causes increased numerical chromosomal abnormalities in the manner that increased maternal age does. However, as males age, structural spermatozoa abnormalities increase, and affected sperm usually cannot fertilize eggs.

The literature suggests a 0.3%-0.5% risk of autosomal dominant disease in offspring of fathers aged 40 years or older. Autosomal dominant disorders include neurofibromatosis, , achondroplasia, and polycystic kidney disease.

Paternal age has been identified as a significant predictor of schizophrenia. Studies have also indicated a possible association between advanced paternal age and offspring with autism spectrum disorders. The American Society of Reproductive Medicine recommends an age limit of 50 years for semen donors.

Any family with a history of birth defects should seek individual genetic counseling. To determine whether an individual has a family history of risk, patients should inform their clinician or genetic counselor about any birth defects that have occurred in the past 3 generations.

What Are Heart Palpitations In Pregnancy

Heart palpitations cause your heart to feel like its pounding, racing or beating too quickly. Your heart rate might speed up, slow down or skip a beat. Some people feel like they have an extra heartbeat.

Heart palpitations in pregnancy are very common. During pregnancy, the amount of blood in your body increases significantly. Your heart works harder to pump the extra blood throughout your body and to your baby. This extra work can result in heart palpitations.

Although they can be alarming, most pregnancy heart palpitations arent dangerous. They usually go away after delivery. Less commonly, heart palpitations can be a sign of a serious health problem, such as arrhythmia . If you have palpitations along with chest pain, trouble breathing, dizziness or confusion, get immediate medical help.

Why Do Women Get Varicose Veins During Pregnancy

Is it normal during pregnancy to have a high heart rate?

Varicose veins are more common as women age weight gain, the pressure on major venous return from the legs, and familial predisposition increase the risk of developing varicose veins during pregnancy. These can occur in the vulvar area and be fairly painful. Rest, leg elevation, acetaminophen, topical heat, and support stockings are typically all that is necessary. Determining that the varicosities are not complicated by superficial thrombophlebitis is important. Having a venous thromboembolism in association with superficial thrombophlebitis is rare. Hemorrhoids, essentially varicosities of the anorectal veins, may first appear during pregnancy for the same reasons and are aggravated by constipation during pregnancy.

Cardiac Signs And Symptoms During Pregnancy

Signs of heart disease may occur during pregnancy. Symptoms include:

  • Trouble breathing while lying down
  • Palpitations

Note that these symptoms do not always signal heart problems. For instance, you may faint due to blood pressure and volume changes in pregnancy. Shortness of breath and trouble breathing while lying down may be caused by the growing uterus. Palpitations may occur because the diaphragm shifts up in the chest during pregnancy. This causes the heart to sit higher in the chest. If you have any of these symptoms at rest during pregnancy, though, see your healthcare provider.

A heart murmur and ankle swelling are also common during pregnancy. Nearly 90% of pregnant women develop a heart murmur. This may be due to the increased volume of blood flowing through the heart. Only your healthcare provider can tell you if these symptoms are normal or due to heart disease.

What Is A Target Heart Rate

Your heart rate is the speed at which your heart beats. It beats slower when you are resting and faster when you exercise. Because of this, you can use your heart rate to measure the intensity of your exercise. For every age group, there is a target heart rate. The target heart rate is the rate your heart beats during good aerobic exercise. By monitoring your heart rate and comparing it to your target range, you can determine whether you are exercising too hard or not hard enough. When you exercise, you should aim to reach your target heart rate and stay within that range for 20 to 30 minutes.

You can measure your own heart rate by taking your pulse. To do so, place your index and middle fingers on the wrist of your other hand, just below your thumb. You should be able to feel a pulse. Count the heartbeats for 60 seconds. The number you count is your heart rate, in beats per minute. You can also purchase a digital heart rate monitor to keep track of your heart rate for you.

You can find the target heart rate for your age from the American Heart Association website.

Why Do Women Undergo Skin Pigmentation Changes During Pregnancy

Pregnancy can cause strange heart symptoms

Pigmentation changes are directly related to melanocyte-stimulating hormone elevations during pregnancy. Some evidence suggests that elevated estrogen and progesterone levels cause hyperpigmentation in women. This is typically evident in the nipples, umbilicus, axillae, perineum, and linea alba, which darkens enough to be considered a linea nigra. More than 90% of patients have skin darkening. Facial darkening, called melasma, is a diffuse macular facial hyperpigmentation. When melasma occurs as a result of pregnancy, it is known as chloasma. This is due to the pigment being deposited in the epidermis itself. The distribution is usually malar but can be central or mandibular. Ultraviolet light exposure intensifies melasma and appropriate sunscreen decreases the effect. Because it is related to the hormones of pregnancy, it lessens with delivery.

Other pigmentation changes, such as palmar erythema, pseudoacanthosis nigricans, vulvar or dermal melanocytosis, or postinflammatory hyperpigmentation secondary to specific dermatologic conditions of pregnancy, are fairly common as well.

Cardiovascular Disorders That May Develop During Pregnancy

Peripartum cardiomyopathy

Peripartum cardiomyopathy is a rare condition. It is when heart failure develops in the last month of pregnancy or within five months after delivery.

Women with peripartum cardiomyopathy have symptoms of heart failure. After pregnancy, the heart usually returns to its normal size and function. But, some women continue to have poor left ventricular function and symptoms. Women with peripartum cardiomyopathy have an increased risk of complications during future pregnancies, especially if the heart dysfunction continues.


About 6% to 8% of women develop high blood pressure, also called hypertension, during pregnancy.
