Adenomyosis

What adenomyosis actually is

In adenomyosis, tissue like the endometrium grows into the muscle wall where it does not belong.

That misplaced tissue still responds to your hormones. So every month it thickens and bleeds — but it is trapped inside the muscle with nowhere to go. The blood cannot escape. The muscle around it becomes inflamed, swollen and tender.

This explains almost everything about the condition:

• The pain is different because it is bleeding inside muscle, not shedding from a surface. Women describe it as heavy, dragging and deep rather than sharp cramping.
• The uterus becomes enlarged — often two to three times normal size — because the muscle is swollen and thickened throughout. This is why your abdomen may look distended.
• Bleeding is heavy because the enlarged uterus has a larger lining surface and contracts less efficiently.
• It worsens over time because the process is progressive.

The symptom picture, and why it worsens with age

Fibroids can be stable for years. Ordinary period pain does not usually escalate. Adenomyosis gets worse — reliably, gradually, year after year.

Women describe it something like this. In their late twenties, periods were manageable. By thirty-two, the first day required a painkiller. By thirty-five, one day off work each month. By thirty-eight, two days, clots, and bleeding for seven days instead of four. By forty, planning life around it.

At every stage they were told this was normal. And at every stage there was a diagnosable, treatable condition getting slowly worse.

The typical picture:

• Progressively heavier periods, often with clots
• Pain that begins two to three days before bleeding starts — this is a strong clue and quite different from ordinary period pain, which begins with the flow
• Deep, dragging, pressure-like pain rather than sharp cramping
• A bulky abdomen, worse around the period
• Pain during intercourse, particularly deep pain
• Periods lasting longer than they used to
• Fatigue from developing anaemia
• Sometimes an urge to pass urine more often, from an enlarged uterus pressing on the bladder

Is adenomyosis cancer?

I am placing this high on the page because it is the question most women actually want answered, and it should not be buried at the bottom.

There is one caveat worth stating clearly. Heavy or irregular bleeding always needs proper evaluation, because several conditions cause similar symptoms and some of those do need excluding — particularly after the age of forty, and always after menopause. Having adenomyosis on your report does not mean nothing else needs checking. But adenomyosis itself is not dangerous in that way.

Adenomyosis or fibroids?

That single anatomical fact is why fibroids so often have a uterus-preserving surgical option and diffuse adenomyosis often does not.

And they frequently occur together — which is one of the main reasons adenomyosis is missed. The fibroid is seen, treated, and the adenomyosis causing most of the symptoms is never identified.

Why adenomyosis gets missed

It does not show up well on routine scans. A standard abdominal ultrasound will often report a “bulky uterus” and nothing more. That phrase appears on thousands of reports and is routinely ignored — but a bulky uterus is a finding, and findings have causes.

It needs a specific look. A transvaginal ultrasound performed by someone who knows the features of adenomyosis is far more reliable. There are recognised sonographic criteria — asymmetrical thickening of the uterine walls, small cysts within the muscle, an indistinct junctional zone, a characteristic striated appearance. If nobody is looking for these, nobody finds them. Where doubt remains, MRI is the most accurate test.

The symptoms have been normalised. Heavy, painful periods are so accepted in India that women do not report them and doctors do not probe. The condition is not hidden. We are simply not looking.

What to do about it: if your symptoms fit, ask by name. “Could this be adenomyosis? Can we do a transvaginal scan and look for it specifically?” Naming the condition changes the examination you receive.

Focal or diffuse — the distinction that decides everything

Focal adenomyosis sits in one defined area, sometimes forming a mass called an adenomyoma. Because it has a relative boundary, it can sometimes be excised surgically while preserving the uterus.

Diffuse adenomyosis is spread throughout the uterine wall. There is no boundary to cut around.

Any honest conversation about your options starts with knowing which you have. If nobody has told you, ask.

Treatment options

Tranexamic acid during bleeding days reduces flow. Anti-inflammatories such as mefenamic acid reduce both pain and bleeding, and work best started a day or two before the period rather than after the pain arrives — a small change that makes a real difference.

Many women manage well on this alone for years.

The hormonal IUD

For a great many women with adenomyosis, this is the single most effective treatment that does not involve surgery. It releases hormone directly into the uterus, keeping the lining thin, which substantially reduces both bleeding and pain.

It lasts around five years. Fertility returns immediately on removal.

The same caution as elsewhere: expect irregular spotting for the first three to six months. Give it six months or do not begin. Women who abandon it in month two never find out whether it would have worked.

Other hormonal treatment

Combined pills, progestogens, and — in specific circumstances — medications that temporarily suppress ovarian function. The last group is generally used short-term, often before surgery, because of side effects with longer use.

Focal excision

Where adenomyosis is focal, surgical removal preserving the uterus is possible. It is technically demanding — the boundary is less clear than with a fibroid, and the uterine wall needs careful reconstruction — but it is a genuine option and should be discussed if your disease is focal.

Uterine artery embolisation

Reducing blood supply to the uterus can improve adenomyosis symptoms in selected women. Evidence is less established than for fibroids, and it is generally not first choice for women planning pregnancy.

Hysterectomy

Here I am going to be direct with you, because I would rather be honest than encouraging.

For diffuse adenomyosis, in a woman who has completed her family, where medical treatment has genuinely been tried and failed — hysterectomy is the definitive cure, and it is a reasonable choice. There is no way to remove the disease and leave the uterus behind. Pretending otherwise would waste your time.

But three conditions attach to that sentence, and all three matter.

Diffuse, not focal. Family complete. And genuinely tried and failed — meaning the full ladder, not one tablet for two months.

If you have been sent straight to hysterectomy without the intermediate steps, that is worth questioning. Not because surgery is wrong, but because you deserve to arrive at it having exhausted the alternatives rather than skipped them.

And there is one more consideration that is easy to overlook. Adenomyosis is oestrogen-driven, and it improves substantially after menopause. If you are forty-seven and manageable on treatment, waiting a few years is a legitimate strategy rather than avoidance. The condition has an expiry date.

Adenomyosis and fertility

Adenomyosis can affect fertility. The altered uterine muscle appears to interfere with embryo implantation, and it is associated with a somewhat higher risk of certain pregnancy complications.

But many women with adenomyosis conceive and deliver normally, and this needs saying clearly because the internet is frightening on this subject.

What matters most: if you are planning a pregnancy, say so before any treatment decision is made. It changes everything — which medications are appropriate, whether surgery is advisable, and how urgently to proceed. Some treatments are incompatible with conceiving, and some decisions are difficult to reverse.

Living with adenomyosis

Practical things that genuinely help, alongside medical treatment:

Start pain relief early. Anti-inflammatories work considerably better begun a day before bleeding than after the pain has established. This one change helps more women than almost anything else I suggest.

Heat helps and there is no reason not to use it.

Watch your iron. Check haemoglobin and ferritin. Persistent tiredness with heavy periods is usually iron deficiency, not simply a busy life.

Track your cycle. Two months of notes — pain, day it started, pads used, what you had to stop doing — will tell me more than a scan report.

Tell someone. A great many women carry this alone, take leave without explanation, and are thought unreliable at work. It is a medical condition, and it is allowed to be discussed as one.
