Unexplained weight loss often belongs in the same pattern as constant thirst and frequent urination and early diabetes symptoms in NL.

About our editorial standards · How we evaluate supplement information

I waited too long because I kept trying to turn every symptom into something ordinary.

The weight loss? Stress. The thirst? Too much coffee. The tiredness? Work. The toilet trips? Maybe I was drinking more water.

That was the little story I kept telling myself until Sophie stood in the bathroom doorway one morning and said, “Mark, your face looks different.” Not thinner in a nice way. Tired. Hollow. Like something inside me had been running quietly for months.

That was the moment I finally booked an appointment with my huisarts in Haarlem.

Dr. Van Dijk did not panic. That helped. He listened, asked about my weight, thirst, urination, sleep, family history and vision. Then he said something that stayed with me:

Unexplained weight loss is not something we guess about. We test.

That sentence cut through weeks of my nonsense. If you are dealing with losing weight without trying and possible diabetes symptoms in the Netherlands, here is the version I wish someone had told me earlier.

When to Seek Care

Call 112 immediately if you have symptoms that feel life-threatening, such as severe chest pain, severe shortness of breath, fainting, signs of stroke, confusion, or extreme weakness.

Go to SEH / acute zorg if you are vomiting repeatedly, severely dehydrated, breathing in a deep or unusual way, rapidly getting worse, or feeling seriously unwell.

Call the HAP / huisartsenpost outside normal huisarts hours if your weight loss comes with intense thirst, frequent urination, vomiting, weakness, or symptoms that feel too worrying to wait.

Book a huisarts appointment if you are losing weight without trying, peeing more often, feeling unusually tired, noticing blurred vision, or seeing slow-healing cuts or infections.

Do not wait until the symptoms become dramatic. Diabetes often does not enter the room shouting. Sometimes it sits quietly in the corner while you keep making excuses.

Lifestyle Steps

After the appointment, I expected Dr. Van Dijk to give me one big answer. Instead, he gave me something more annoying: small steps.

He asked me to stop trying to “fix everything” before the blood test. No crash diet. No panic fasting. No pretending I could reverse weeks of symptoms by buying expensive green juice and becoming a better person by Thursday.

So I started simple.

I wrote down my weight every few days. I tracked how often I was peeing, when I felt thirsty, whether my vision changed, and how tired I felt after meals. It made the problem feel less like a ghost and more like a pattern.

I stopped drinking sweet drinks during the day. Not because one drink was evil, but because if high blood sugar was part of the story, I did not need to add fuel to the fire.

I started eating proper meals again. Real food. Not “coffee and whatever I found at 3pm”. Simple, but surprisingly important.

I also looked at a diabetes risk test after reading that Diabetesfonds encourages early checking and prevention in the Netherlands. That was the first time I realised this was not just “my weird symptom”. A lot of people may be walking around with high blood sugar and no idea.

And that is where I became interested in support beyond the huisarts appointment.

Not miracle cures. Not fake promises. But practical support: food, movement, blood sugar awareness, and yes, supplements people talk about for metabolic health. I did not want to be sold magic. I wanted to know what was actually worth looking at and what was just expensive dust in a capsule.

That is why in the next article I started looking into top diabetes supplements in the Netherlands: what people use, what may support a healthier routine, what has evidence, and what you should avoid if a brand promises too much.
