Hello, I am Dr. Hong Myeong-hwi, Chief Physician at HyungInJae Korean Medicine Clinic Gangnam.

Some people notice swelling in the hands, feet, or face before a period, want different foods than usual, or find that their sleep timing changes. When these changes repeatedly begin in the days before menstruation and ease after bleeding starts, the pattern is a useful clue to a possible cycle link. One or two episodes, however, cannot diagnose premenstrual syndrome or another condition.

During consultation, I do not bundle every symptom into one conclusion. I separate timing, the location of swelling, appetite and meals, and sleep and day-to-day function. If practical, use the same fields over two cycles. Warning signs should take priority over completing the diary, so do not delay medical care to collect more entries.

First, record the cycle day and when each change begins and eases

Count the first day of menstrual bleeding as cycle day 1, then mark when swelling, appetite changes, and sleep changes begin and ease. Use the same scale, such as 0 to 10, for symptom intensity. Add one line about the effect on work, study, exercise, or relationships. Comparing the same fields across two cycles can make it easier to see whether changes recur at a similar time.

A pattern that begins before menstruation and settles afterward supports looking at a cycle link, but it is not a diagnosis. Symptoms that persist regardless of cycle timing or become progressively worse may need appropriate medical evaluation for other possibilities, including anemia, thyroid conditions, medication effects, and sleep or mood disorders.

Second, distinguish the location, side, and time of swelling

Note whether swelling affects the face, hands, or both ankles and whether it is more noticeable in the morning or evening. Include whether rings or shoes feel tight, pressure leaves an indentation, or the change follows prolonged sitting or a salty meal. A brief note at a consistent time may be less burdensome than weighing yourself every day.

Swelling that appears similarly on both sides before a period and then eases is different from sudden swelling and pain in only one leg, especially with redness or warmth. The latter needs same-day medical assessment for causes such as a blood clot. If chest pain or breathlessness occurs as well, call emergency services or go to an emergency department immediately.

Third, log hunger and meal timing as well as food preferences

Record when appetite changes, hunger before eating, whether the amount eaten differs from usual, and any skipped meals. Rather than noting only a desire for sweet or salty foods, add whether lunch was delayed and whether caffeine, alcohol, or stress occurred around the same time. This gives the history useful context.

The diary is not a scorecard for good or bad eating. Appetite changes alone do not establish hormone status and should not be turned immediately into a weight-loss plan. If loss-of-control eating, vomiting, laxative use, severe restriction, or intense anxiety about food and weight recurs, do not tighten restrictions on your own. Discuss it with an appropriate clinician or eating-disorder professional.

Fourth, include sleep timing and next-day function

Write down bedtime, estimated time to fall asleep, nighttime awakenings, and wake time. The same 0-to-10 scale can describe how next-day sleepiness, poor concentration, or mood changes affect daily life. One line is enough for factors that may disrupt sleep, such as late caffeine, night shifts, or pain.

Sleep may increase or decrease before a period, but not every sleep change is caused by the menstrual cycle. If depression, anxiety, or anger becomes severe enough to disrupt daily life, or if thoughts of self-harm occur, do not wait for the next period. Seek prompt help from an appropriate mental health service. For immediate danger, call emergency services or go to an emergency department.

Pregnancy possibility, unusual bleeding, or severe pain needs assessment first

If a period is late or pregnancy is possible, do not assume that bleeding and abdominal pain are ordinary premenstrual symptoms. Pregnancy possibility together with severe one-sided lower abdominal pain, shoulder-tip pain, dizziness or fainting, or bleeding unlike a usual period needs prompt obstetric, gynecologic, or emergency assessment to exclude urgent causes such as ectopic pregnancy.

Seek appropriate medical assessment for bleeding that is much heavier than usual and requires ongoing pad or tampon changes every 1 to 2 hours, especially with large clots, marked dizziness, or breathlessness. Sudden severe pelvic pain or pain that prevents ordinary activity also warrants evaluation. A diary for a Korean medicine consultation does not replace diagnosis or emergency assessment, and no Korean medicine outcome can be promised in advance.

Frequently Asked Questions (FAQ)

How many menstrual cycles should I track?

If practical, use the same fields for two cycles so recurring timing is easier to compare. Do not wait to complete a diary if you have severe pain, unusual bleeding, possible pregnancy, or an emergency warning sign.

Does swelling and increased appetite before a period mean PMS?

A recurring pattern that starts before menstruation and eases afterward is a clue to a cycle link. A symptom diary alone cannot make a diagnosis; duration, effect on daily life, and other health conditions also need consideration.

Is sudden swelling and pain in one leg just a premenstrual symptom?

Do not treat it as routine cycle-related swelling. Sudden one-sided leg swelling and pain needs same-day medical assessment. With chest pain or breathlessness, call emergency services or go to an emergency department immediately.

Can the diary alone determine a Korean medicine treatment plan?

The diary makes the clinical history more specific; it does not guarantee a diagnosis or treatment result. Current symptoms, medical history, medicines, and pregnancy possibility need assessment before discussing an appropriate scope of care.

※ Symptoms and the appropriate scope of care vary by individual. Consult an appropriate medical service for an accurate diagnosis.
