I Heard My 81-Year-Old Mother Straining Through the Bathroom Door at 4:50am

She was on day 9. I was on day 6. A doctor with a dry-erase marker showed me the one thing happening inside both of us and why she should never have been pushing at all.

I stood in the hallway in my socks with my hand flat on the door and I counted.

Eleven seconds with no breath. Then a gasp. Then quiet. Then she started again.

She had rolled a bath towel along the bottom of the door so the sound wouldn't carry. It carried.

My mother, Ruth, is 81. She moved into our back bedroom 14 months ago, after my dad passed. And that Sunday morning she was on day 9.

I was on day 6. I hadn't told anyone either.

Two hours later a doctor stood at the little whiteboard where they write your nurse's name, and what she said undid the 14 months I had watched my mother suffer and 6 years of my own. It took that doctor four minutes and a marker. Nobody in all that time had drawn it for us.

If someone you love has tried what we tried and is still not right, or if that someone is you, this is for both of you.

The Towel Under the Door

I'm Carol. I'm 58. I've been the secretary at the same elementary school in Fort Wayne for 31 years. My husband Dale retired from the plant 2 years ago.

I want you to see what this looked like in our house, because you'll recognize some of it.

I have timed my body to a school bell for 31 years. Second recess is 10:14. I go then or I don't go at all, because the front office bathroom shares a wall with the nurse.

I have kept a MiraLAX packet folded behind my ID badge so I could pour it into a water bottle at my desk without opening a drawer.

I have chaperoned the fifth-grade trip to the Children's Museum in Indianapolis for 19 years and stopped 3 years ago, because it is 2 hours each way on a school bus with no bathroom. I have told Dale I was "just tired" 4 nights a week for 6 years.

And then my mother moved in, and I started finding her list.

A bank calendar on her nightstand with small pencil dots. It took me 3 weeks to work out the dots were the days she went. Some months there were 5.

A box of senna in the button jar in her sewing basket. Fleet enemas behind the guest towels. "I'm fine, I went," at breakfast on mornings the calendar said otherwise. The Wednesday church lunch she went to for 40 years, quietly dropped.

A bathroom fan that comes on at 4:50 every morning and runs for 35 minutes.

And a towel, rolled under the door.

We had tried what you've tried. Her doctor put her on MiraLAX 3 years ago. When it quit he added senna at night. When that quit he said, "Ruth, this happens with aging," mentioned her blood pressure pill, and moved on to her knees.

Colace. Milk of Magnesia. Prunes by the case. Metamucil, which only bloated her. By August she couldn't fasten her housecoat.

Me: MiraLAX for 6 years. Senna for 4. Magnesium citrate in the green bottle. Metamucil for 5 months. Two colonoscopies, both "clean as a whistle," and the words "slow transit" with a shrug. Linzess at $310 a month that worked for 7 weeks and then didn't. Probiotics at $45 a bottle.

I did the math one night on the back of a field trip permission slip. $6,800, most of it the two colonoscopies. Before her copays.

And by August I was sitting on the edge of my bed thinking: is this what 81 looks like? Is this what 58 looks like? Am I going to be rolling a towel under my own door in 23 years so my daughter doesn't hear me?

Then came the 9 days. I'm not going to dramatize them. Monday she said she went. She hadn't. Wednesday she stopped eating breakfast. Saturday she asked me twice what day it was. My mother has never once in my life asked what day it was.

Sunday, 4:50am. The fan. The towel. Eleven seconds. The gasp. Then her voice through the door, small. "Go back to bed, Carol."

I did not go back to bed. We drove her to the ER with her housecoat over her nightgown. She had 9 days packed inside her and nothing from a box was going to move it. It had to be dealt with right there, that morning. I'm only going to write about that once. My mother apologized to the nurse the entire time.

By 7 it was over and she was asleep. I was in the chair by the window, not asleep.

"I Want to Talk About the Sound You Heard Through the Door"

At 7:10 the doctor came in. Dr. Lindqvist. About my age. Fellowship in geriatric medicine, covering the weekend.

She didn't stand over my mother's bed. She pulled the rolling stool over to my chair, sat down, and said:

I hadn't told her about the sound. "Everyone who brings a parent in on day 9 has heard it," she said. "Let me show you what's making it."

She uncapped a marker and drew a tube on the whiteboard, under the nurse's name.

"This is her colon. It has one job on the way out. Pull water back out of what's passing through. That's it."

"At a normal speed that works out fine. Just enough water comes back out. Soft. Easy. Slow everything down — age, a blood pressure pill, a lifetime of sitting — and the colon gets more time than it needs. So it keeps doing its one job. It takes too much."

She drew the tube narrowing. "What's inside goes from soft to dry to stone. Once it's stone, it's stuck. Then every day of sitting costs it a little more water. The stone gets harder. The cycle tightens."

"And here's what nobody told either of you. The water she drinks does not fix this. The small intestine takes it up first, well upstream of the trouble. Her colon never sees it."

She capped the marker. "Does your mother keep plants?"

"Geraniums. On the back porch."

"Then she knows this. A pot that's gone bone dry in August. You water it from the top and it runs straight down the gap between the dirt and the pot and out the bottom. The middle stays dust. You have to set it in a saucer and let the water come up from underneath."

"That's her colon. Everything you've given her has been poured on top."

Why She Should Never Have Been Pushing at All

She uncapped the marker again. "Now the sound."

"When she holds her breath and bears down against that stone, the pressure inside her chest climbs. The blood coming back to her heart drops. Her blood pressure falls, and when she lets go it jumps."

"A 30-year-old shrugs that off. Your mother is 81, on a blood pressure pill, alone, on a tile floor, with the door locked."

I started to ask what it could cause. "I'm not going to list it," she said. "You already looked it up on your phone while she was asleep." I had.

Then she went through everything we'd tried, one thing at a time, and told me why each one had failed.

"And her blood pressure pill," she said. "Do not stop it. It's not the cause. It's the nudge that tipped a slow colon into a stalled one."

Her doctor wasn't wrong to say her age. He was wrong to stop there. The tests they ran rule out the dangerous things, and they did. But "this happens with aging" is the sentence that closes the file. In a 14-minute appointment, the drawing on that whiteboard does not happen.

Water From Underneath

"So what does work?"

"Magnesium oxide, at a real dose. Not the little tablet from the drugstore aisle."

"About 4 percent of it absorbs into the blood. The other 96 percent never leaves the gut. And a mineral that stays put has only one thing it can do. Water follows it through the wall, into the stone. Not around it. Into it."

"In Japan it has been the first thing a doctor prescribes for constipation since the 1980s. About ten million people take it."

Then she told me why I'd never seen magnesium work. "That green bottle was the right mineral in the wrong form. It leaves before it can soak. You were closer than you knew."

She wrote on the whiteboard under the tube. What to look for:

"Read labels," she said. "At bedtime, two capsules. A full glass of water with them. If she needs more, go up by two."

What I Found at the Kitchen Table

I stopped at the Walgreens on the way home. Every magnesium oxide on that shelf was a 250 milligram tablet with binders. I stood there for 10 minutes and drove home.

That night at the kitchen table I read labels on my phone for an hour. Gummies at 100 milligrams. Tablets at 400 with fillers. One that wouldn't say whether it was tested.

I understood the shelf by then. Nobody wants to put a real dose in a capsule with nothing else in it. It costs more to make and it doesn't fit in a gummy.

One met all four. Magnesium oxide, 1,400 milligrams, in capsules, with two ingredients. It said ozonated, third-party tested and Non-GMO Project Verified on the bottle. Made in the USA.

I looked her numbers up too. A study in 2001, Firoz and Graber, on the 4 percent. She had it right. Then a Japanese trial: 7 in 10 responding against 1 in 4 on a sugar pill, inside the first week.

It was called WaterBack.

It isn't a stimulant and it isn't a fiber. It's the Japan dose of magnesium oxide in a capsule. Water from underneath.

If you're expecting fireworks, this isn't it. There is no cramping. None of that senna business that wakes you at 2am. It works while she sleeps, and by morning the body has done its own job again, for free.

Two capsules at bedtime. A full glass of water with them, a couple of hours after supper. My mother started on two. So did I. Neither of us has needed four.

What Happened in Our House

I ordered two bottles from the kitchen table. One for her. One she didn't know about. They came Monday.

There is no senna in the button jar. No boxes behind the towels. No packet behind my badge. The pencil dots stopped in September. She stopped counting.

The Reviews I Read Twice Before I Clicked

What It Costs, Against What We Were Paying

I spent $310 a month on Linzess that quit after 7 weeks. $45 a bottle on probiotics. 6 years of MiraLAX at $11 a box every 3 weeks. My mother gave up her Wednesdays.

One bottle of WaterBack is $47.98. That's 60 capsules, 30 nights at two. Two bottles is $67.99, which works out to $1.13 a day. Three bottles is $79.96, which is 89 cents a day.

Get two. Bottle one is where you find out it's real. Bottle two is where you stop standing at doors. Three is for the person you'd roll a towel for. For her, and for you. Or both for you. Nobody has to know.

Give it 90 days. If your mornings haven't changed, you get the full purchase price back. That was the part that let me click.

Neither of you is failing at this. She isn't old. You aren't weak. There is water missing from a place nobody looked, and you can put it there tonight.

Don't wait until she asks what day it is. Don't wait until you are standing in a hallway in your socks, counting. Don't wait until the towel.

Questions You're Probably Asking

I drink water all day. Why hasn't it helped?

Because a glass of water is taken up in the small intestine. The colon never sees any of it. Drying happens downstream of the glass. Magnesium oxide works from inside the colon, pulling water through the wall into the stool itself. Watering from underneath, not the top.

Can men take it?

Yes. Same colon, same stone, same two capsules. Dale started in week five.

My mother is 81 and on blood pressure pills. Can she take this?

Mine is, and she does. Start with two capsules, not four, and go up by two only if she needs it. Take it at bedtime, at least 2 hours after her last meal, as the label says. If she takes prescription medicines, ask her pharmacist about spacing them apart. Do not stop her blood pressure pill.

What do I take, and how soon does it work?

Two capsules at bedtime. A full glass of water with them. One bottle is 60 capsules, so 30 nights at two. If you don't get a soft, complete morning, add two the next night. In the Japanese trial the difference showed inside the first week. In our house it was the first morning for her and the second for me.

Is this alright to keep taking?

It works by water, not by force. The class where the muscle tires and the dose creeps up is the stimulant one — senna, Dulcolax and the rest. Magnesium oxide brings the water in, and the bowel does the rest itself. It has been prescribed daily in Japan for four decades. If you have kidney problems, ask your doctor first.

And if it does nothing for me?

Give it 90 days. If your mornings haven't changed, you get the full purchase price back. That's the whole guarantee.
