When to tell a date about your health

If you're living with a health condition and dating again, you've probably rehearsed this conversation in your head more times than you'd like. Diabetes, MS, a heart condition, Crohn's, a cancer that's behind you, depression you manage well. Say it too early and you worry it's the only thing they'll remember. Say it too late and it can feel as if you were hiding something.

Here's the short answer. Your health is part of your story, and you get to choose when it comes up. For most conditions, most people prefer to hear about it after a few dates, once you both know you like each other. The exceptions are when it affects the plans you're making right now, like food, drink, travel, activities or getting physical. Then you tell sooner, briefly and calmly. Below is a timing guide by situation, with sample lines you can borrow.

First, some perspective. In 2023, 78.4% of Americans aged 35 to 64 had at least one chronic condition and 52.7% had two or more (CDC). And 18.6 million Americans were living with a history of cancer as of January 2025, 79% of them aged 60 or older (American Cancer Society). If you're dating in midlife, the person across the table very likely has something going on too.

The fear, and what the research says

The fear is real, and it's common. In a UK survey by Abbott, the company that makes the FreeStyle Libre glucose monitor, 58% of dating app users with a health condition said they were unlikely to share it, and 32% of people said they see those with health issues as less attractive partners (Abbott). That's a company survey, so treat it as a signal, but it shows how many people carry this worry.

There's more hopeful evidence too. In an experiment with members of three Dutch dating websites, a profile that mentioned a cancer history drew almost the same interest as one that didn't, and the researchers described the difference as negligible (PLoS ONE). The same paper then asked young Dutch medical students, in two further experiments, when they'd want to hear about a cancer history. The most common answer was after a few dates, and no more than 5% wanted to know before a first date (PLoS ONE). It's one study, from the Netherlands, about one illness, and the timing answers came from students rather than daters. Still, it points the same way as this guide: timing and tone do a lot of the work.

A timing guide by situation

In your profile

You don't have to mention it. A profile is a first hello, and most people leave out their medical history the same way they leave out their bank balance. Some people do prefer to be upfront, especially about something visible, like a wheelchair or a prosthetic, or something central to their week. That's a perfectly good choice too, and it filters out the wrong people early. If you do, keep it light and matter-of-fact, the way you'd mention a hobby. A sample: "Type 1 diabetic, keen hiker, terrible at crosswords."

Before the first date: only if it affects the plan

If your match suggests a wine tasting and you don't drink because of a medication, or a long hike and your knees say no, a short practical line is enough. You don't need to give the reason.

You could say: "I don't drink, but I'd love to do coffee or a walk by the river." Or: "Long walks are hard for me. Could we try a café or a gallery instead?"

On the first date: if it's visible or affects the evening

If you'll be checking your blood sugar, taking a pill with dinner, using a mobility aid or skipping certain foods, a brief, unbothered mention keeps it from turning into a mystery.

You could say: "I'm diabetic, so I'll just check my levels before we order. It takes a second." Then carry on. Matter-of-fact tends to get matter-of-fact back.

After a few dates: the fuller conversation

For most conditions that don't show, the right moment is once you've had a few dates and you both clearly want more. You're starting to talk about the future in small ways, and it would feel odd for them not to know.

You could say: "There's something I'd like you to know, because I like where this is going. I have MS. Day to day, it mostly means I get tired more easily and plan around that. I'm happy to answer any questions, now or later."

That shape works for almost anything. Say it plainly, say what it means for daily life, invite questions, then stop talking. You don't owe a full medical history, and you don't need to apologize.

Before getting physical

If your condition, treatment or medication affects sex, your body or your energy, or if there's anything a partner needs to know for their own health, tell them before you get to the bedroom, never after. Our guide to sex after a long gap includes a short script for the testing conversation, which works here too.

Sooner, if it will shape the weeks ahead

If you're in active treatment, newly diagnosed or facing surgery soon, earlier is usually kinder, because it will affect your plans and your energy in the coming weeks. The same goes for anything that could change a plan at short notice. A simple line covers it: "I've got some treatment going on at the moment, so I may need to move things around. I'll always tell you why."

Mental health

Depression, anxiety, bipolar disorder and other mental health conditions follow the same rules. You don't owe it on a first date. If it's well managed, it can wait until you know each other. If it will affect how often you can see each other, or how you show up in a hard week, it's kinder to both of you to mention it as things get serious.

How much to say

Less than you think. A date needs to know what it means for the two of you, and the full medical file can wait, perhaps forever. Three things cover almost every conversation: what it is, how it affects ordinary life, and what, if anything, you'd want them to do. "If I go quiet and pale, I need sugar. There are glucose tablets in my bag." Practical details like that are a kindness to both of you.

You also get to set the limits. "That's about as much as I want to go into tonight, but ask me anything another time" is a complete answer.

What a good reaction looks like

How someone responds tells you a lot, and it's one of the clearest green flags you'll ever get. A good reaction sounds like a thank you, a question or two that comes from curiosity rather than fear, and then a return to normal. Later, maybe, they quietly look up your condition, or check the menu for you before you have to ask.

A poor reaction can take a few forms: going quiet and disappearing, making jokes at your expense, turning into your doctor, or asking whether you'll be "a burden". It stings. It's still useful to learn this about someone early rather than late. Our guide to green flags that matter more after 40 has more signs to look for.

Some people need a day to think. A slightly awkward first response followed by a kind message the next morning is a good sign too, so give it a little time before you decide.

If you're the one being told

Thank them. Ask what it means day to day, and whether there's anything they'd like you to do. Then carry on with the date. You don't need the perfect response. You just need to show it hasn't changed how you see them.

A note on advice

This guide is about dating, and it's general information. For anything about your condition, your treatment or what's safe for you, talk to your doctor. If worry about dating with a health condition is weighing on you, a counselor, ideally one who works with people living with long-term illness, can help you find your footing.
