Irregular or Missing Periods

A cycle that arrives when it likes, or not at all, is telling you something. Reading it is the first job.

Cycles shorter than 21 days, longer than 35, wildly variable, or absent for three months or more all count as irregular, and each pattern has its own likely causes. Chinese medicine treats the cycle as a readout of the whole system and works to give it back its rhythm.

Understanding
irregular periods

A regular cycle needs the hypothalamus, pituitary, and ovaries to talk to each other on schedule, and a lot can interrupt the conversation: PCOS, thyroid disease, high prolactin, weight change, intense exercise, chronic stress, and perimenopause among them. Amenorrhea, the absence of periods, warrants a physician's evaluation to rule out those causes, and heavy bleeding needs one too.

In Chinese medicine, the cycle's timing and flow map to specific patterns: early periods to heat or Qi deficiency, late periods to cold or blood deficiency, irregular timing to liver qi stagnation, the stress-driven pattern, and absent periods often to blood deficiency or phlegm-damp. The old menstrual disorders page describes the practice's approach as supporting the endocrine glands that balance estrogen and progesterone, the circulation of the blood that carries them, and the liver function that clears them.

The pattern, read from your history, tongue, and pulse, decides the points, the formula, and the food.

Amenorrhea and irregular cycles are treated with the same hormonal support that stabilizes the whole cycle.

A regular cycle is the first step to conceiving, so this is where fertility care often begins.

How we work on it

Under menstrual disorders, treatment is a weekly series with a Chinese herbal formula prescribed to your pattern and whole food nutrition between visits. Acupuncture is used to calm the stress response, which suppresses the HPO axis when it stays high, and to support circulation to the uterus; a course of treatment has been shown to lower cortisol and shift the autonomic nervous system toward rest-and-digest. What happens at a first visit describes how the pattern is read.

When the cycle is irregular because of PCOS, or when the reason you are here is that you want to conceive, the same work continues as fertility care, planned in three-month blocks to match the roughly 90 days a follicle takes to mature. A cycle that ovulates predictably is the first goal either way.

What to expect, honestly

Acupuncture may help regulate ovulation, particularly when cycles are stress-driven or irregular, and small studies in women with PCOS report more frequent ovulation after a course of treatment. It does not treat thyroid disease, a pituitary tumor, or premature ovarian insufficiency, and it is not a substitute for the blood work that finds them. Our PCOS article is honest about where the evidence is strong and where it is not.

Expect to plan in months, not weeks. Because the cycle you are in started forming three months ago, we look for change over that window: cycle length, ovulation signs, flow, and premenstrual symptoms. Dr. Schiff has treated women's health for over 20 years, and if the underlying cause turns out to be perimenopause, the plan shifts to match.

Where we would start.

Questions we hearfrom patients dealing with irregular or missing periods.

It may help when the cause is stress, weight change, or PCOS, by supporting the HPO axis and reducing cortisol. It does not treat thyroid disease, high prolactin, or premature ovarian insufficiency, so a physician's blood work comes first to rule those out.

We plan in three-month blocks, because the cycle you are in started forming about 90 days ago. Some women notice sleep, stress, and premenstrual symptoms shift within weeks; cycle timing usually takes longer, and we track it across the window.

Heavy or prolonged bleeding needs a physician's evaluation first, because fibroids, polyps, and clotting problems have specific treatments. Once those are addressed or ruled out, Chinese medicine treats heavy flow as its own pattern with acupuncture and herbs.

Not necessarily, but they make timing harder and often signal that ovulation is irregular. A cycle that ovulates predictably is the first goal of treatment whether or not you are trying, and if you are, the same care continues as fertility support.
