Heavy periods and flooding in perimenopause: why it happens, and when to worry

In perimenopause, periods often get heavier and can flood because ovulation becomes erratic — when you don't ovulate, oestrogen goes unopposed by progesterone and the womb lining thickens, so it sheds heavily. This is common and usually benign. But heavy bleeding also has other causes worth ruling out, and a few bleeding patterns are genuine red flags. You are not overreacting by getting checked, and you do not have to tolerate soaking through your clothes every month.

Is heavy bleeding normal in perimenopause?

Heavier, more unpredictable periods are one of the most common changes of perimenopause. Here's the mechanism, plainly: in a normal cycle you ovulate, and the empty follicle then makes progesterone, which matures and eventually organises the shedding of the womb lining. In perimenopause, ovulation gets skipped more and more. In a cycle where you don't ovulate, you still make oestrogen — which keeps building the lining — but little progesterone to hold it in check. The lining grows thicker and more unstable, so when it finally comes away, the bleed is heavier, longer, and more prone to clots and flooding.

So yes, heavier periods can be an expected part of the transition. "Normal for perimenopause" is not the same as "nothing to check", though — because fibroids, polyps and lining changes cause the same picture, and they get commoner at exactly this age.

How heavy is too heavy?

Forget vague impressions — use concrete signs. Bleeding is medically heavy, and worth seeing a doctor about, if you have any of these:

• Soaking through a pad or tampon every hour or two, for several hours.
• Needing double protection (pad plus tampon) to get through.
• Passing clots larger than a 2-euro coin.
• Flooding through to clothes, chairs or bedding.
• Signs of anaemia from blood loss: breathlessness, dizziness, unusual tiredness, pale skin, a pounding heart.

Anaemia is the quiet cost of heavy periods that most women underrate — running low on iron for months explains a lot of the exhaustion. It's worth asking your doctor to check your ferritin (iron stores); see menopause blood tests in Malta for what that involves here.

What helps heavy perimenopausal periods?

The reassuring part: heavy bleeding is treatable, and there is a real range of recognised options — from non-hormonal medicines that reduce flow, to hormonal approaches that thin the lining or steady the cycle, through to procedures where those don't suit. Which is right depends on your bleeding pattern, whether you still want contraception, your other symptoms and what's found on assessment.

We'll stop short of prescribing a route here — that's a decision to make with a doctor who has examined you, and the sequenced version lives in the paid kit. The first move is simpler and entirely yours: track a few cycles (dates, how heavy, clots, any bleeding in between), so you walk in with specifics instead of "they're just really bad."

Getting heavy bleeding assessed in Malta

Two Malta-specific facts to route you:

• The public pathway is a GP referral. There's no dedicated menopause clinic — your health-centre or private GP refers you into Mater Dei's Gynae Outpatients (Msida; Mon–Fri 07:30–12:30; free/subsidised for residents, booked in person with a GP referral). Assessment there may include an examination and a pelvic ultrasound to look at the lining, fibroids or polyps.
• Ask about ferritin. Doctor-ordered bloods are free for residents at health centres and Mater Dei Pathology; privately, labs quote at booking. Heavy bleeding plus fatigue is exactly the case for checking iron stores, not just a full blood count.
