Pregnancy Week 17: Symptoms, Hormonal Changes, Fetus Growth
In the 17th week of pregnancy, expectant mothers may notice several changes in their bodies and the developing baby. This period marks a significant milestone in the pregnancy journey, with the baby growing and developing rapidly.
### Common Symptoms
During the 17th week, expectant mothers may experience increased appetite as the growing fetus requires more nourishment. Weight gain is also common, with expectant mothers gaining about 1 to 5 pounds (0.5 to 2 kg) during this week. Other common symptoms include skin changes such as melasma and the linea nigra, sciatic nerve pain, indigestion, and frequent urination. Many women can now feel slight fetal movements called quickening, although first-time mothers may mistake these sensations for gas[1].
### Hormonal Changes
Hormonal shifts contribute to the increased appetite, skin pigmentation changes, and symptoms like indigestion and headaches earlier in the second trimester. These hormones support fetal development and prepare the body for childbirth, but also influence mood and physical symptoms[1][2].
### Baby Development Milestones
By the 17th week, the baby is about 5 inches long, resembling a nail buffer, and weighs approximately 5 oz. The baby is growing coordination in its hands, and the nervous system and muscles are developing, allowing movements such as making a fist and possibly pulling the umbilical cord. The baby’s circadian rhythms begin to develop, and they can open and close their eyes, responding to external stimuli[1][3][4].
### Recommended Exercises
Light to moderate physical activity is encouraged to maintain health, improve circulation, and reduce discomfort like leg cramps and back pain. Safe exercises include walking, swimming, and pregnancy yoga, avoiding extreme sports and activities with a high risk of falling or pressure on the abdomen. Avoid exercises involving lying flat on the back for extended periods or twisting the upper body sharply. Activities such as scuba diving, mountain climbing, or adrenaline-heavy sports should be avoided altogether[2].
### Lifestyle Changes
Maintaining a balanced, nutritious diet is essential to meet increased calorie needs (about 2,100 to 2,500 calories daily depending on body weight and activity). Protecting skin from sun exposure is crucial to prevent worsening of pigmentation changes, and using sunscreen is recommended. Managing symptoms like sciatic pain with appropriate posture adjustments, gentle stretching, and consulting a healthcare professional if needed is also important. Monitoring any varicose veins or leg cramps and seeking advice if they cause significant discomfort or risk of complications is also recommended[1][2][3].
### Vitamin D Supplementation
Women who are pregnant should be taking a 400-800 International Unit (IU) supplement of vitamin D every day to help strengthen the bones of the fetus[5].
### Fetal Development
At week 17, the fetus's bones in the ears are changing and growing daily, and the fetus's fingers have developed the lines that form its fingerprint. The fetus is starting to pick up on sounds and voices, and the fetus's eyes can move though they will remain shut. The fetus is growing eyelashes and eyebrows, and an adipose layer, a crucial part of its metabolic system, is developing[6].
### First-Time Feeling the Fetus Move
Many women can now feel the fetus moving for the first time at around 17 weeks, although first-time mothers may mistake these sensations for gas. As the bump becomes more visible, expectant mothers may start feeling more confident[7].
### Potential Complications
Symptoms of pregnancy complications can include leaking vaginal fluid, vaginal bleeding or passage of tissue, faintness or dizziness, low blood pressure, rectal pressure, shoulder pain, severe pelvic pain or cramping. If any of these symptoms are noticed, contact your physician immediately[8].
These combined approaches help ensure the health and comfort of both mother and baby during the 17th week of pregnancy.
- In some cases, expectant mothers may encounter a blockage in their health-and-wellness routine due to pelvic pain, which can be managed with appropriate posture adjustments and consulting a healthcare professional.
- As the baby grows and develops during the 17th week, it is essential for expectant mothers to take a daily vitamin D supplement of 400-800 International Unit (IU), as this nutrient aids in the baby's bone development, particularly in the fetus's ears.
- During this period, it is crucial for women's health to maintain a balanced diet rich in nutrients to accommodate the increased calorie needs and support the baby's growth, as well as to protect the skin from sun exposure to prevent worsening pigmentation changes. regular application of sunscreen is recommended.
