Refresh page after action

I have a function to change records in the database and use a modal to show success message or change error.

The issue is that I can delete, but I would like to have the page automatically refreshed after this function.

elseif(isset($_GET['Acao']) && $_GET['Acao'] == 'Alterar') {
   $Id = $_GET['Id'];
     $sql = mysql_query("UPDATE vendas SET Mostrar = '0' WHERE Id = '$Id' ");

     if ($sql){
       echo '<script>modal({type: "inverted", title: "INFORMAÇÃO!", text: "Aterado com Sucesso!"});
       </script>';}
      else {  
        echo '<script>modal({type: "error", title: "Ops!", text: "Erro ao Alterar!"});</script>';             
}

<table class="lista-clientes" width="100%""> 
<tbody>     
    <tr>
        <td align="center"></td>
    <td> 

    <select class="select_styled">
        <option value="">'.$dados['Pessoa'].' </option>
        <option value="">'.$dados['Venda'].'</option>
    </select>
    <center>
        <a href="?Id='.$dados['Id'].'&Acao=Alterar" class="btn btn-follow" style="text-decoration:none;">
            <span>Remover!</span>
        </a>
    </center>
    </td>
    </tr>
 </tbody>
</table>
