One of the common symptoms that affect pregnant women from the very beginning of pregnancy is headaches. Even if the pain is mild, it can still be quite bothersome. Many women start searching for ways and tips to relieve it, although in some cases, it may signal a more serious issue.
Pregnancy headaches are a common problem, and in some cases, they can be reduced by understanding their causes. In an interview with obstetrics and gynecology consultant Dr. Maryam Safwan, four simple yet effective tips were shared to help reduce pregnancy headaches, including going outdoors and using pain relievers within safe limits.
What Hormonal Changes Occur in a Pregnant Woman’s Body?
Hormonal Headaches During Pregnancy
The first hormonal changes begin as soon as pregnancy is confirmed. The body starts producing the pregnancy hormone, scientifically known as human chorionic gonadotropin (hCG), which is secreted by the placenta after the fertilized egg implants. This hormone supports the function of the corpus luteum, which produces progesterone.
Higher levels of hCG may indicate a twin pregnancy, although elevated levels can sometimes point to other conditions as well.
Progesterone secretion begins early in pregnancy and continues from the 8th to the 12th week. It helps stimulate the growth of blood vessels in the uterine lining, preparing it for implantation and supporting the embryo. It also prevents uterine contractions, reducing the risk of miscarriage.
Estrogen also plays a role after pregnancy is established. It helps regulate progesterone levels and increases blood flow to nourish the fetus. However, it may also cause mild physical symptoms such as nasal congestion and headaches.
Hormonal changes aim to stabilize the pregnancy. Relaxin levels rise significantly during the early months, preventing uterine contractions and improving blood flow to the kidneys and placenta, which supports fetal health.
Prolactin is also produced during pregnancy. Although it is responsible for milk production after birth, during pregnancy it mainly increases breast size and causes a feeling of heaviness. It also supports fetal development and boosts the mother’s immune system.
Headaches are common during the first trimester due to these hormonal changes. Increased blood volume, fatigue, lack of sleep, stress, hunger, dehydration, and poor nutrition can all contribute to headache episodes.
4 Tips to Reduce Pregnancy Headaches
1. Use Pain Relievers Carefully
You may take safe pain relievers prescribed by your doctor to reduce headache symptoms. However, they should be used in moderation—no more than one tablet per day. Overuse or taking unsuitable medication may lead to fetal abnormalities or increase the risk of miscarriage. In later months, excessive use may cause premature birth and complications.
2. Avoid Tightly Wrapping the Head
Some women tie a cloth tightly around their heads to relieve headaches, but this can worsen the pain. Tight pressure affects blood vessels in the brain and may reduce blood flow, potentially impacting both the mother and the fetus.
3. Go Outdoors
It is important to stay active during pregnancy. Walking outdoors is one of the safest and easiest exercises, especially in early pregnancy. Start with short walks and gradually increase the duration.
Walking helps reduce stress, improves mood, enhances blood circulation, and strengthens muscles, all of which can help reduce headaches.
4. Eat Dark Chocolate
A simple yet effective remedy is eating a small amount of dark chocolate. It may help reduce the risk of high blood pressure, which can cause headaches. Moderate consumption can also lower the risk of digestive discomfort and anemia, both of which can contribute to headaches and dizziness.
When Is a Pregnancy Headache a Concern?
A headache becomes concerning if it persists, worsens, or prevents you from carrying out daily activities despite following advice. It may be a sign of high blood pressure during pregnancy.
High blood pressure can be accompanied by swelling in the face, hands, and feet, indicating fluid retention and increased protein levels in the urine. This may lead to a condition known as preeclampsia, which requires medical supervision and sometimes hospitalization.
In severe cases, it may affect liver and kidney function and even impact the fetus, requiring continuous monitoring and possibly early delivery as decided by doctors.
