Dear Doctor: My daughter is 16 weeks pregnant with her second child. Her father and I can tell that she's really feeling down, even though she's been trying to hide it. I thought that women get the baby blues after giving birth, not during pregnancy. Is there anything I can do to help her?

Dear Reader: We read and hear a lot about postpartum depression, a form of clinical depression related to the physical, emotional and hormonal changes that accompany childbirth. However, the changes to mood that take place during pregnancy itself, known as perinatal depression, are not nearly as well known. That's unfortunate because an estimated 14 to 23 percent of pregnant women experience some level of depression during pregnancy.

For most of them, it will go unaddressed. Some women say that having symptoms of depression during pregnancy, a time that popular culture associates with joy and anticipation, causes them to feel shame. For many, the physical changes that take place while carrying a baby can obscure the bigger picture of their mental health. That's because a surprising number of symptoms that are common to pregnancy, such as changes to sleep patterns, decreased energy levels, a loss of appetite and a drop in libido, are also common to pregnancy.

Whether it's due to a reluctance to admit to depression, or that the symptoms of the condition have been obscured, the end result is that a significant percentage of women who experience depression during pregnancy don't get help. This can be dangerous to the mother and her baby, and it can adversely affect her family as well. Regular prenatal care is important to the well-being of both mother and child. When someone is depressed, though, making and keeping a series of appointments can be overwhelming. The same goes for eating a healthful diet and getting proper exercise, both of which can take more attention and planning than someone who is depressed can muster on a daily basis. Depression during pregnancy can adversely affect existing relationships, such as with children and spouses. It can interfere with a mother's ability to bond with her new infant after birth, and it is linked to an increased risk of going on to develop postpartum depression.

The American College of Obstetricians and Gynecologists recommends that women get screened for depression at least once during pregnancy. However, anyone who suspects she is experiencing perinatal depression shouldn't wait for her health care provider to take the lead. In the case of your daughter, the fact that she hasn't been successful at hiding her underlying distress from the family makes it likely she realizes something is amiss.

One of the things you can do to help is start talking to her about it. Urge her to open up to her doctor, and if possible, offer to take her to the visit. When people are depressed, necessary self-care can often fall by the wayside.

Should depression be diagnosed, her doctor will discuss treatment options. These include individual psychotherapy, support groups, bright light therapy and, in certain cases, medication. The important thing is to start the conversation and let her know she won't be going through this alone.

Woman's Blood Pressure Drops Significantly After Meals

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Ask the Doctors | January 18th, 2019

Dear Doctor: I am an 86-year-old female, and sometimes, about an hour after eating a meal, my blood pressure drops significantly, from a normal of 123/74 to as low as 93/47. When it happens, my lips tingle and get dry, and I feel "zonked" out, like I'm in some kind of a trance. What causes this? What can I do?

Dear Reader: What you've described is known as postprandial hypotension, which means that someone's blood pressure drops measurably in response to eating. (Postprandial refers to the time after a meal, and the "hypo" in hypotension refers to low blood pressure.) The condition is common in older adults and is estimated to be present to some degree in up to 30 to 40 percent of the elderly. It is also often found in people living with Parkinson's disease. Because the condition can lead to dizziness, falls and fainting, and in some cases can result in angina, stroke or heart attack, it's important that it be diagnosed and addressed.

Each time we eat, we require our circulatory system to reorganize and recalibrate its activities. That's because the tasks of digestion and absorption create the need for additional blood flow to the stomach, particularly the small intestine. To accommodate that need, blood vessels throughout the body that are not involved in the digestive system begin to narrow. This allows blood to be redirected to the stomach and small intestine, while still maintaining consistent blood pressure throughout the body. To aid in those dual goals, the heart beats faster. As the stomach and intestines complete their work, blood vessels dilate again, and the heartbeat returns to normal.

In people with postprandial hypotension, blood flows as needed to the digestive organs. However, the circulatory system doesn't respond with the appropriate measures. For reasons that aren't yet clear, the heart rate doesn't increase enough, and blood vessels do not narrow enough to compensate for the redirected blood flow. That results in a drop in blood pressure and the symptoms you described.

Since low blood pressure can lead to a loss of consciousness and a fall, as well as the more serious complications we mentioned earlier, it's important that you address this with your family doctor. It sounds as though you've been tracking your blood pressure with a home monitor, and your doctor will want to see those readings. She or he will also want to follow up with a definitive diagnosis, which entails a baseline blood pressure reading before a meal, and then up to two hours of post-meal blood pressure monitoring.

People who take blood pressure medications may be asked to make changes to how and when they take the drug. But please don't make any changes without your physician's input.

Lifestyle changes may include a pre-meal cup of coffee, as caffeine can cause an increase in blood pressure. A large glass of water before a meal has also been shown to be helpful. Diet may play a role too, as postprandial hypotension has been linked to meals high in carbohydrates. It's a good idea to track what you're eating and see if the food correlates to episodes of low blood pressure.

Oral Immunotherapy Shows Promise in Treating Peanut Allergies

Ask the Doctors by by Eve Glazier, M.D. and Elizabeth Ko, M.D

Dear Doctor: My 5-year-old nephew has a severe peanut allergy. It's so bad that he can't risk eating anything that isn't prepared by the family. Even the highly supervised snack time at school isn't safe. Now I've read about a new peanut allergy drug that is an oral immunotherapy. How does it work? Do you think it could help him?

Dear Reader: We are parents as well as physicians, so we understand the nonstop vigilance that comes with a food allergy. But peanuts are common enough that, despite a family's best efforts, it's likely a child with a peanut allergy will come into contact with them at some point. That's why the potential of the new immunotherapy drug you mentioned is so exciting. Not only does it offer people with peanut allergies a new measure of protection, it opens up a range of possibilities for future allergy therapies.

The new drug, currently known as AR101, is under review by the Food and Drug Administration. This follows the completion of a series of clinical trials in the efficacy and safety of the drug. AR101 works by very gradually exposing an individual to peanut proteins, which desensitizes the immune system. This takes place over the course of six months, during which the peanut content in the daily oral dose is methodically increased. At the end of a year -- six months of treatment followed by six months of maintenance -- 67 percent of the children in the study were able to safely eat two peanuts. Researchers have made it clear that the goal is not to cure the allergy, but to reduce the severity of symptoms should accidental exposure to peanuts ever take place.

Unfortunately, the drug didn't work for everyone. More than 10 percent of the participants exited the study before it was complete due to adverse reactions. Of those who remained, 14 percent required intervention with epinephrine, which eases symptoms. The bad news for adults living with a peanut allergy is that the treatment was not effective in those adults who were enrolled in the clinical trials.

For those who aren't aware, peanut allergy is one of the most common causes of severe allergy attacks in children. A reaction can be triggered by even a tiny amount of the legume, and symptoms range from mild to severe. They include runny nose, itching or tingling in the mouth and throat, hives or other skin reactions, gastric distress like nausea, vomiting or diarrhea, and respiratory issues like wheezing, shortness of breath or a tightening of the throat. At its most severe, a peanut allergy can cause anaphylaxis, a life-threatening reaction that is causing an increasing number of hospitalizations. Symptoms include swollen airways that prevent breathing, a precipitous drop in blood pressure and loss of consciousness.

A challenge of the treatment is that after receiving each daily dose of the medication, children have to rest for two hours but cannot sleep during that time. Still, physicians and researchers are buoyed by the results. AR101 has been flagged by the FDA as a breakthrough therapy, which makes it eligible for a swift approval process. If all goes well, the manufacturer reports that the drug could be available by the end of 2019.
