Why is it so expensive to swap on Uniswap?

Could you please elaborate on the reasons behind the high costs associated with swapping tokens on Uniswap? Are the transaction fees disproportionately high compared to other decentralized exchanges? Is there a specific mechanism in place that contributes to these costs, or are they simply a result of the current market conditions? Additionally, are there any steps that users can take to minimize these fees when swapping on Uniswap? Your insights would be greatly appreciated.
