If you have been offered hormone treatment, or you are already taking it, you may have come across the terms sequential and continuous. They can sound clinical, but the difference is straightforward. These describe two ways of taking estrogen and progesterone together. The one which is right for you usually comes down to where you are in perimenopause or menopause and whether you are still having periods.

The basics

Hormone treatment for women who have a womb typically involves both estrogen and progesterone. Estrogen is the hormone that improves most symptoms such as hot flushes, night sweats, low mood and brain fog. Progesterone is needed to protect the lining of the womb from becoming too thick. If you have had a hysterectomy, you may be able to take estrogen on its own.

The question of sequential versus continuous is specifically about how progesterone is given.

Sequential hormone treatment

Sequential hormone treatment, which is sometimes called cyclical, means you take estrogen every day, but progesterone for only part of the month. This produces a withdrawal bleed, similar to a period, when the progesterone phase ends.

It is most often prescribed for women who are still having periods, or who are in perimenopause where periods have become irregular, lighter, heavier or more unpredictable. The rationale for this is because your body is still producing some of its own hormones. Some women find the regularity of a monthly bleed reassuring. Others find it inconvenient, particularly if their own cycle is already disrupted.

Continuous hormone treatment

Continuous hormone treatment means taking both estrogen and progesterone every day, with no monthly break. The aim is to avoid a regular bleed.

This type is usually prescribed once you are postmenopausal. That is, after 12 consecutive months without a period. Many women prefer it because it removes monthly bleeding and is simpler to manage. Women with premature ovarian insufficiency can also take continuous treatment; being a certain age is not a requirement.

Which is right for you?

In general, sequential treatment is more likely if you are still in perimenopause with periods. Continuous is more common once you are postmenopausal. But treatment should not be determined by age or a checklist alone. Your symptoms, bleeding pattern, medical history and personal preference all matter.

If one form of progesterone causes low mood, bloating or a premenstrual feeling, it is worth knowing that different forms of progesterone exist and that switching can sometimes make a significant difference.

If you are considering conception, then sequential hormone treatment may be advised.

Some women swap from sequential to continuous over time as their menopause progresses. Others stay on sequential treatment for longer because it continues to suit them. There is no single right answer, just what works best for you and your body.

What to expect when you start

Improvement is not always immediate. It typically takes around three months for symptoms to settle after starting hormone treatment, or after changing the dose or type. Hot flushes and night sweats often improve within a few weeks, while low mood, joint pain and vaginal dryness may take longer.

Bleeding is common at the start, particularly as your body adjusts. Breast tenderness can occur too, linked to both estrogen and progesterone, and often settles within six to eight weeks. Bloating, headaches or premenstrual-type feelings can also happen early on, usually related to progesterone or hormonal adjustment. These often improve as levels stabilise.

Your starting dose is unlikely to be your final dose, especially in perimenopause when your own hormones are still fluctuating. Side effects with body identical hormones are not very common, and when they occur they often settle over time.

When to ask for a review

If symptoms are not improving after a few months, or if side effects are not settling, it is worth going back to your family doctor or menopause specialist. Shared decision-making matters. your symptoms are enough reason to ask for a review, and finding the right treatment often takes more than one appointment.

Needing an adjustment is not failing. For many women, it takes time to arrive at the dose and type that works best.
