The side effects really depend on the dose and how long you take it, but something nobody mentioned is that some weird symptoms can show up after you stop the treatment, like mood swings or fatigue, because your body got used to that corticosteroid.
The swelling and increased appetite are real, yeah, but it doesn't hit everyone the same way - some people notice minimal changes and others have a rough time.
The important thing is that if it was prescribed to you, you talk to whoever prescribed it about how to manage the side effects while you're taking it.
Dexamethasone is a strong corticosteroid and yeah, it does have pretty noticeable side effects, especially if you take it for a long time. I'm not a doctor, but I've seen up close how it works in several people close to me. Weight gain is real, but it really depends on how long you use it and at what dose. What happens is that corticosteroids increase your appetite quite a bit and change how your body distributes fat, typically in your face, neck, and back. If you take it for just a few days for acute inflammation, you probably won't notice much change. But if it's for weeks or months, then yeah, it starts to show.
The other side effects are serious too: they can mess with your sleep, your mood, your blood sugar (especially if you're already predisposed to diabetes), they can weaken your bones if you take it for a long time, and there's a risk of infections because you're lowering your immune system. Some people also report anxiety, irritability, or emotional changes. What happened to a coworker of mine was that dexamethasone caused her terrible insomnia and digestive problems along with the weight gain.
That said, sometimes it's necessary and the benefits outweigh the risks, so it's not like you should refuse it if your doctor prescribes it. The important thing is that you take it exactly as directed, don't prolong the treatment longer than necessary, and follow your doctor's instructions. If they prescribe it for you, ask them specifically for how long and what you can do to minimize those effects (diet, exercise, etc). There's quite a bit of information out there about how to manage this better than there was years ago.
Don't self-medicate with this or stop taking it without talking to your doctor, even if you notice side effects.
What they don't mention as much is that weight gain varies quite a bit depending on the dose and how long you use it, but it also depends on each person - some people tolerate it better than others.
The important thing is that if they prescribed it to you, talk to your doctor about how to manage the side effects while you need it, because sometimes the benefits justify the temporary changes to your body.
Man, dexamethasone does make you gain weight quite a bit, especially if you take it for more than 2-3 weeks straight.
It's a potent corticosteroid (about 25-30 times stronger than natural cortisol) and what it does is increase your appetite, retain sodium and fluids, and change how your body distributes fat, typically toward your face and neck. The side effects are serious: insomnia, mood changes, weak immunity, osteoporosis if you stay on it long-term... that's why doctors give it at low doses and for the shortest time possible.
If they've prescribed it to you, ask your doctor straight up how long it's going to be and if there are alternatives, because those effects are real.
